JavaScript does not have a built-in unsigned integer data type, so to convert a signed integer to an unsigned integer, you can use the (>>>) operator. This is because the (>>>) operator always fills the leftmost bit with a zero, effectively converting the number to an unsigned integer...
JavaScript Bitwise OperatorsThe bitwise operators in JavaScript perform operations on the integer values at the binary level. They are used to manipulate each bit of the integer values. Bitwise operators are similar to logical operators but they work on individual bits. ...
JavaScript (Zero Fill) Bitwise Left Shift (<<) This is a zero fill left shift. One or more zero bits are pushed in from the right, and the leftmost bits fall off: DecimalBinary 500000000000000000000000000000101 5 << 100000000000000000000000000001010 (10) ...
In this tutorial, we will be exploring how to use bitwise operators in JavaScript. JavaScript’s Bitwise operators are probably the most tricky to understand, especially when you are new to programming or computer science.

The table below defines the JavaScript bitwise operators. Applications of bitwise operations and operators There are many applications of bitwise operations and operators. For one, they are used indata compressionwhere data is converted from one representation to another to reduce the amount of storage...
The following table summarizes JavaScript's bitwise operators: Signed 32-bit integers The operands of all bitwise operators are converted to signed 32-bit integers in two's complement format. Two's complement format means that a number's negative counterpart (e.g. 5 vs. -5) is all the numb...
