Exploring Bitwise Operators in JavaScript | PART - 1 | #js #javascript #reactjs #nextjs #jsx #basics

Bitwise operators in JavaScript are used to perform bitwise operations on integer operands at the binary level. These operators manipulate the binary representation of numbers, allowing developers to work with individual bits.

Here are the main bitwise operators in JavaScript:

1. **Bitwise AND (&)**: Performs a bitwise AND operation on each pair of corresponding bits. Returns 1 if both bits are 1, otherwise returns 0.
2. **Bitwise OR (|)**: Performs a bitwise OR operation on each pair of corresponding bits. Returns 1 if at least one bit is 1, otherwise returns 0.
3. **Bitwise XOR (^)**: Performs a bitwise XOR (exclusive OR) operation on each pair of corresponding bits. Returns 1 if the bits are different, otherwise returns 0.
4. **Bitwise NOT (~)**: Flips the bits of its operand. Inverts each bit from 0 to 1 and vice versa.
5. **Left Shift **: Shifts the bits of the left operand to the left by a specified number of positions. Zeros are shifted in from the right.
6. **Sign-propagating Right Shift **: Shifts the bits of the left operand to the right by a specified number of positions. The sign bit (MSB) is used to fill the vacant positions from the left.
7. **Zero-fill Right Shift **: Shifts the bits of the left operand to the right by a specified number of positions. Zeros are shifted in from the left, and the sign bit is discarded.

Bitwise operators are commonly used in scenarios such as low-level programming, cryptography, and optimization algorithms where manipulation of binary data is required.

Understanding how bitwise operators work and their application can significantly enhance your ability to work with binary data and perform optimizations in JavaScript.
