How to Learn to Code in 2021 – 10 Free Websites For Learning Coding

With 2020 keeping us home for extended periods of time, more and more people are growing their skillsets online. Learning online is affordable, flexible, and easily personalized.

The benefits are clear but the outcomes are profound - students, remote workers, academics, and builders are all benefiting from online learning. I even taught myself new technical skills from the resources that follow.

This learning led me to build a website from scratch for people and students to work from home. Pretty cool, right?

With the right resources and tools, you too can achieve learning outcomes that translate into immediate results and help you build products.

But finding all of the right tools to enhance your education in one place is hard. This article addresses that: by making it easy to find all of the resources you need to learn how to code in one article, I hope that you can start learning sooner.

How does online learning work?

Some people are skeptical about learning online. The old-school thought is that you need 1:1 lessons, real time feedback, and collaboration among peers.

But guess what? All of those core benefits are now online. One of my best friends is not in technology, but practices law. He told me about his time in law school practicing and deploying the Socratic method.

This form of cooperative argumentative dialogue between individuals, based on asking and answering questions to stimulate critical thinking, helped him retain material, deeply understand core concepts, and practice.

These websites deploy a similar set of experiences for users: you are forced to learn, practice, engage, actually code, see your mistakes, understand what you have done well, and track your progress.

Much like the Socratic method, these websites hone your critical thinking skills. And they are relentless in their focus on improving your general aptitude to see problems, recognize patterns, and ultimately improve.

Without further ado, here are the best free, most reliable, educational websites for learning how to code.

freeCodeCamp

freeCodeCamp is a non-profit organization in the United States, dedicated to helping people learn to code for free.

Through their content, which includes interactive coding tutorials supported by videos and articles, they have assisted 40,000 learners in landing their dream jobs in companies like Google, Spotify, Microsoft, and more.

You can get certifications by completing courses in various categories. freeCodeCamp offers content on Web Design, Quality Assurance, Data Visualization, Machine Learning, and other additional topics. They also cover coding adjacent frameworks such as Agile/Scrum methodologies .

In addition to the 3000 hour (free) curriculum, they have a popular YouTube channel and technical publication .

This website is one of the best references for students, employees, or managers to grow their skills and keep up with the newest in their fields.

It offers free courses, tutorials, and a ton of resources on almost anything you would like to learn. These options are compiled and taught by professors from the top universities from all over the world.

You can explore so much coding-centric content on Coursera . It’s worth noting that if you want certifications through Coursera, you will hit their paywall.

However, you can learn an introduction to programming, HTML, CSS, loT programming, C language, Python, Java, and more for free from a beginner’s level or higher.

Coursera also has non technical content, which can help you understand a broader array of topics including product design, digital marketing, and even tax planning. All interesting and relevant content.

Codecademy is a platform dedicated specifically to coding. According to their website, 45 million learners have developed their coding skills through their website in only seven years.

You can start your Codecademy learning journey by evaluating your coding skills in order to find out which level suits you the best. Or, if you are a beginner, get ready to begin coding within minutes.

Their learning software allows you to learn by doing, aka ‘practice makes perfect’. With instant testing of your coding skills, you are assured that you are correctly applying what you are learning.

They offer great tool tips and real time feedback to unblock you as the learning modules increase in difficulty.

You have a variety of options with the subjects you could learn including Web Development, Data Science, Computer Science, Machine Learning, Web Design, Game Development, and Mobile Development.

You can also start learning languages right away with courses on HTML & CSS, Python, Javascript, Java, SQL, C++, PHP, and more.

edX offers free online courses by esteemed and reputable universities like Harvard, MIT, Georgetown, the University of British Columbia, and more. They have several categories to choose from but if you are after learning coding, you will definitely find the ones for you.

I recommend you check out their Computer Science and Data Science categories for in-depth courses on Full Stack Development, Javascript, Python, AI, Machine Learning, and more.

To get a verified certificate, you will have to pay. There are also some courses that require paying but for the most part, you could learn a great amount just by attending the free courses.

Udemy is quite a unique learning platform since it is the home to the world’s largest collection of courses. Well, that’s because all of their content is user-generated so your instructor can be an expert, a professor, or a fellow coder.

There are plenty of free and paid courses regarding the web development world. While choosing the course for you, make sure to check the ratings that others have given - that’s generally a decent barometer on how you should prioritize courses.

Then, start learning Design, IT, Software Development, and level up from beginner to professional.

This platform provides a wide range of free and paid courses that help learners perfect their desired skills by practicing in real life projects. That aids in landing a job right after improving your professional and technical skills.

You have free range with the time you need to master your next tech skill as well as the liberty to choose from their diverse options. Their categories include Programming, Data Science, Artificial Intelligence, Cloud Computing, and more.

W3Schools is one of the oldest and largest online schools. It’s really great if you want to brush up on current schools. I highly recommend their SQL tutorial. It works to not only assist you in learning coding but also in consistently re-learning certain syntaxes and commands.

I used to reference their SQL documentation on a regular basis when I was starting out.

So even if you are a coding professional, W3Schools is filled with references and examples to help you stay on top of your game at all times. They also have a pretty decent video library of tutorials.

You can always go for their paid alternative for a certification. But if you are just a beginner, you can easily grasp a lot from this platform. Whether you choose HTML & CSS, Javascript, PHP, Python, Java, or any of the diverse languages available, you will be coding in no time.

A former colleague used this site to learn how to build an SMB server as he was brushing up on his devops skills. The content that you can learn and practice is, in other words, immediately applicable.

This amazing platform has transformed learning to code into something very social and interactive. SoloLearn works to create a community of developers where learners can interact, collect points, and appear in their ‘Top Learners’ section.

It is available both on the web and on a mobile application so you can learn anywhere, anytime. In addition, you can become part of the conversation. You can ask questions, answer other people's questions, and have fun with other learners on the ‘Code Playground’ and ‘Discuss’ sections.

With courses on Python, C++, Java, Javascript, SQL, PHP, HTML & CSS, React, Angular, and pretty much anything code-related you could think of.

Microsoft Learn

Microsoft is now offering a new platform that presents an interactive experience to learn technical skills that compliment Microsoft products and services including Azure, Microsoft 365, Microsoft Dynamics, and more.

Microsoft Learn helps learners get hands-on with coding whether they are at beginner or advanced levels.

Learners can choose to stay online and learn at their own pace or join instructor led lessons. Of course, you always have the option to get certified by the platform.

This platform is one of a kind in its function and application. If you would like to find multiple courses from different sources at the same place, look no further than Hackr.io.

The website’s algorithm allows anyone to post their course, but with votes from users, the best ones get upvoted to the top. You can use filters to drown out the irrelevant courses and tutorials and only pick from the ones that match your needs.

Conclusion: Learning to Code via free websites

When you learn online, you are empowered to move at your own pace, explore topics more deeply that you care about, and harness the power of virtual communities to accelerate your understanding of foundational topics.

Building a list of the top resources takes some digging and some guess work. You need to ask questions, poke around, and try the sites out. Use this list as your guide, but do your own digging as well.

These websites are not only educational resources - they are products unto themselves. That means that they have strengths and areas for improvement. I love building products and by using an array of these websites I have improved my abilities and aptitude.

I hope these sites help with whatever you are building, be it technology to stream videos, building a web app for yourself, or using technology to cultivate communities around shared interests.

You now have your stepping stones for learning coding, so start your journey and make a shift for 2021.

What’s the purpose.

What's the purpose?

Ever since the Industrial Revolution severed our connection to the positive results of our very own hands’ work, “purpose” has fallen prey to many skepticisms, including the following:

• “It’s a millennial trend.”
• “What control could I possibly have toward the major problems I see in the world?”
• “I don’t have time to think about my purpose; it’s what I’ll focus on when I retire.”
• “It’s just a shallow branding exercise.”
• “The problems I care about are too complicated to understand how my contributions matter.”
• “I like my life too much to start thinking about the impact it has.”
• “I wrote a purpose statement once in a leadership program a few years ago.”

Do any of these unhelpful associations live in your understanding of purpose? Allow me to share with you why I don’t believe any of them are valid.

Purpose Is Not Overwhelming

When you go to a party, you don’t have to be the lead dancer, bartender, or wallflower; you only have to play your role. Similarly, your purpose doesn’t have to address all the world’s problems or even its biggest ones.

Indeed, purpose-driven leaders are clear about which problems they care about solving and what specific solutions they are able to contribute to. During a moment of overwhelm at the scale and complexity of the problems facing his employees and customers, Shawn Riegsecker, founder and CEO of Basis, realized that “Successful people spend their time in a circle of influence, not their circle of concern.”

You don’t need to work on every issue you’re concerned about; you can successfully work on only the issues that are within your influence. Since nearly eight billion people have been invited to this Purpose Party, each of us is free to get exactly that specific about our contributions. As soon as we each understand how to address the 1/8,000,000,000th (one eight-billionth!) of the world problems that fit into our circle of influence and start taking action, we’re on our way to a better world!

Purpose Is Not Complicated

What if we defined purpose as “a reason to get up in the morning”? Actually, the Japanese word for purpose, ikigai, translates best to exactly that phrase. And they’re not the only ones to have thought about our so-called modern trend of living with purpose. A wide array of thinkers, organizations, and philosophies define purpose as the intersection of our unique strengths and interests with the needs of the world around us. In other words, like a party, purpose is a simple, age-old concept. Purpose is not a modern trend, and it doesn’t have to be complicated.

In his 2009 TED talk, which has been viewed 50 million times, Simon Sinek referred to purpose as your why. His work has inspired countless people to create a purpose statement using the formula, “TO ____ SO THAT ____.” In other words, “What you do so you contribute to some better future.”

Particularly in times of fear, loss, and great uncertainty, the mundane framing of purpose as “a reason to get up” can be useful. It’s natural to feel inclined to hunker down, focus on survival, and wait for it all to be over before getting back to existential questions or long-term thinking. But what we really need to get through tough times is a reason to persist. If you’re not sure that’s true, read Viktor Frankl’s Man’s Search for Meaning , which is about how he and fellow concentration camp prisoners were able to survive unthinkable suffering because they had a larger reason to persist, whether it was a music collection, family member, or seed collection to preserve.

In this human framing of purpose, you don’t need an expensive coach or marketing consultant to find yours. It’s just a matter of understanding the activities, people, and outcomes that inspire you to get up every morning. Further, using this simplified definition, it’s not hard to see why purpose is good for team performance as well. Of course employees with purpose are more effective; they get up in the morning to come do their jobs!

Your Purpose Does Not Require Suffering

Living purposefully doesn’t require a life of deprivation or suffering. On the contrary, identifying and pursuing your purpose is the way to true, deep satisfaction. Research shows it also extends your life expectancy by seven years, among other significant physical and mental health benefits.

If you’ve ever hosted a party, you’ve likely experienced the tension between working to make sure your guests have a good time and enjoying the party yourself. Similarly, purposeful leaders must balance their commitment to the outcome they want to make—which could always be more—and protect their own wellbeing. Ultimately, the most impactful people are those who learn to balance their own needs (physical, intellectual, financial, emotional, and spiritual) with their work so that they can perform to their highest capacity for the longest time.

During our interview, Asha Curran gave credit for her deep sense of purpose to her “deeply unconventional parentage.”

"My mother was a poor, single woman in New York City in the ’70s, living through homelessness and poverty. She had great courage, living in line with her own integrity, not what made it easier to fit in. I saw how many of her decisions made it harder for her—having me out of wedlock, giving up financial security—but were best aligned with her values. I was inspired by her, but also very conscious that I don’t want to be a martyr to my values. My upbringing has made me feel very strongly that people shouldn’t suffer in terms of their salary or quality of life to work in the social sector or otherwise pursue their purpose."

While there are often trade-offs in the journey to living purposefully, which we’ll discuss in detail later on, experience and research show unanimously that it’s the only path to true and deep fulfillment.

Your Purpose Is No One Else’s

Going First doesn’t mean you can’t learn from others, be coached, or follow a mentor or role model. You can. We must! But remember the nearly eight billion purpose statements that are floating around globally. To activate your own purpose, you cannot follow the choices and behaviors of others; you must identify a purpose that fits your unique blend of skills, needs, and passions. Your purpose is yours and no one else’s, and you have never existed before.

Biotech entrepreneur Nina Tandon pointed out to me that “No one’s actually the ‘first’; we live in a community of several billion people. And yet every moment is new. The dots that can be connected at a given space-time moment are always new.” This is an important qualification of “first”: your purpose may have echoes of things others have done or aspired to do, but it’s showing up uniquely in this time and space as you.

Your Purpose Is Not a One-and-Done

As you evolve, your purpose will too. Finding your purpose is not a one-time exercise that you accomplish upon graduating college or changing jobs. A lot of the underlying themes, values, and areas of interest may persist throughout life, but the way we understand the problems we care about solving, and the ways we choose to contribute, will evolve significantly. Thus the importance of developing a practice of leading and living purposefully, requires wisdom, tools, and dedication. I am passionate about helping people lead and live in purpose.

Environmental Education, Reading and Fun: Community Event Incorporates Them All

The U.S. Fish and Wildlife Service is committed to creating a lasting base of environmental literacy, stewardship, and problem-solving skills for today's youth. One way the service works towards this goal is by participating in community events where environmental education can be promoted. Wolf Creek National Fish Hatchery is always excited for opportunities in the community to provide such encounters. 

Marsha Hart, Environmental Education and Outreach Specialist at Wolf Creek National Fish Hatchery, attended the local “Read Across Russell County” event held at the Russell County Public Library on March 14, 2024. Wolf Creek NFH, along with other community partners, created an atmosphere where children and youth could have fun while reading and learning about various topics. 

Wolf Creek NFH set up to focus on pollination including topics such as what are pollinators, what is the process of pollination, the importance of pollination, and what can be done to help pollinators. To incorporate reading and fun, participants would spin a large wheel that would land on a question or topic about pollination for them to read aloud, and then answer or discuss the topic. It was wonderful to hear children share what they already know about pollinators, and be eager to learn more! Parents also joined in on the fun, with some telling of flowers they plant that attract pollinators and others telling about enjoying watching butterflies as they move from flower to flower.

The event was a success, with over 450 in attendance. Events like this provide the opportunity for us to join in community partnerships, and engage children and youth in environmental literacy.
