Left Shift Assignment (<<=) Operator in JavaScript
The Left Shift Assignment Operator is represented by "<<=". This operator moves the specified number of bits to the left and assigns that result to the variable. We can fill the vacated place by 0. The left shift operator treats the integer stored in the variable to the operator's left as a 32-bit binary number.
How does the Javascript left shift operator work?
4. Because the return value of this bitwise operation in your JavaScript engine is a signed 32-bit integer that can only represent numbers from -2147483648 to 2147483647. The control of whatever an integer is negative or positive is done by setting the signal bit, the bit of highest relevance in the 32-bits chain (2^31).
JavaScript Bitwise
JavaScript Uses 32 bits Bitwise Operands. JavaScript stores numbers as 64 bits floating point numbers, but all bitwise operations are performed on 32 bits binary numbers. Before a bitwise operation is performed, JavaScript converts numbers to 32 bits signed integers. After the bitwise operation is performed, the result is converted back to 64 ...

left shift assignment · WebPlatform Docs
left shift assignment Summary. Moves the specified number of bits to the left and assigns the result to result. The bits vacated by the operation are filled with 0. Syntax result <<= expression result Any variable. expression The number of bits to move. Examples. Using the <<= operator is the same as specifying result = result << expression
Assignment operators
The basic assignment operator is equal ( = ), which assigns the value of its right operand to its left operand. That is, x = y assigns the value of y to x. The other assignment operators are usually shorthand for standard operations, as shown in the following definitions and examples. Name. Shorthand operator.
JavaScript Assignment
Use the correct assignment operator that will result in x being 15 (same as x = x + y ). Start the Exercise. Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, Python, PHP, Bootstrap, Java, XML and more.
Bitwise Left Shift Assignment (<<=) Expression
How Bitwise Left Shift Operations Work. In a bitwise left shift operation, the value to shift is converted to its binary representation. For example, the decimal (base 10) number 0 (zero) may be converted to the binary form 0000 and the number 1 (one) may be converted to 0001. The bitwise left shift operation will move each bit to the left by ...
Left shift (<<)
Expressions and operators. Left shift (<<) The left shift operator ( <<) shifts the first operand the specified number of bits to the left. Excess bits shifted off to the left are discarded. Zero bits are shifted in from the right. JavaScript Demo: Expressions - Left shift operator. 9.
Bitwise Left Shift(<<) Operator in Programming
The bitwise left shift operator can be used to clear a specific bit in an integer to 0. This is done by left shifting 1 by the desired bit position, taking the bitwise complement (~) of the result, and then using the bitwise AND (&) operator to clear the bit. // Clear the nth bit to 0. int bitmask = ~(1 << n);
Left Shift ( ) Bitwise Operator in JavaScript
Last Updated : 23 May, 2023. JavaScript Left Shift Operator is used to operate on the two operands. The first operand is the number and the right operand specifies the number of bits to shift to the left. The operation is represented by the "<<" symbol. Mainly the left shift operator is used to multiply the number by any power of 2.

Assignment operators
An assignment operator assigns a value to its left operand based on the value of its right operand.. Overview. The basic assignment operator is equal (=), which assigns the value of its right operand to its left operand.That is, x = y assigns the value of y to x.The other assignment operators are usually shorthand for standard operations, as shown in the following definitions and examples.
Multiple left-hand assignment with JavaScript
Assignment in javascript works from right to left. var var1 = var2 = var3 = 1;. If the value of any of these variables is 1 after this statement, then logically it must have started from the right, otherwise the value or var1 and var2 would be undefined. You can think of it as equivalent to var var1 = (var2 = (var3 = 1)); where the inner-most ...
JavaScript
JavaScript (JS) is a lightweight interpreted (or just-in-time compiled) programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. JavaScript is a prototype-based, multi-paradigm, single-threaded, dynamic language, supporting object-oriented ...
What is the JavaScript >>> operator and how do you use it?
15. >>> is the unsigned right shift operator ( see p. 76 of the JavaScript 1.5 specification ), as opposed to the >>, the signed right shift operator. >>> changes the results of shifting negative numbers because it does not preserve the sign bit when shifting.
