JavaScript Bitwise Left Shift Assignment Operators

Perform Bitwise Left Shift Assignment Operations In JavaScript

A bitwise operation takes values and operates at the most basic unit of information whose logical state is represented by 1 or 0.

JavaScript bitwise operators convert numbers to 32-bit integers otherwise it will use BigInt if applicable. Therefore bitwise left shift (<<) binary operation compares each bit of 2 operands and shift the bits of a number to the left and fill 0 on voids left as a result. The format is (number) << (number of shifts) such a 2 << 1 to shift the bits of 2 to the left by 1 so that 0010 for 2 becomes binary 0100 or decimal 4. The left shift operator multiples the number by any power of 2.

An operand is the object of a mathematical operation. Operands for the bitwise left shift are integers in the form of numbers or BigInt and the logical shift leftmost bit depends on the sign of the initial number.
