Checking Odd or Even

In this approach, we are using bitwise AND (&) to check the least significant bit of n. If it’s set (odd), “odd” is printed; otherwise, “even” is printed.

Syntax:

if (num & 1) {
    // num is odd
} else {
    // num is even
}

Example: In this example, we are using the above-explained approach.

Bit manipulation in JavaScript refers to the manipulation and operation of individual bits within binary representations of numbers and JavaScript uses 32-bit signed integers for numeric values. It involves using bitwise operators (&, |, ^, ~, <<, >>) to manipulate individual bits of binary numbers. These operations can be used for bitwise logic operations such as AND, OR, XOR, and shifting bits.

Below is a list of bitwise operators:

• Bitwise AND(&): Returns true if both operands are true.
• Bitwise OR(|): Returns true even if one operand is true.
• Bitwise XOR(^): Returns true if both operands are different.
• Bitwise NOT(~): Flips the value of the operand.
• Bitwise Left Shift(<<): Shifts the bit toward the left.
• Bitwise Right Shift(>>): Shifts the bit towards the right.
• Zero Fill Right Shift(>>>): Shifts the bit towards the right but adds 0 from the left.

Below we will describe the common bit manipulation problems in detail:
