WebJun 20, 2024 · The final bitwise operator that JavaScript supports is the unsigned right-shift operator (>>>). This operator is represented by three greater-than signs (>>>). The operand on the left will be shifted by right value. Zeroes will be pushed from the left, with excess bits on the right being dropped. WebAug 5, 2024 · The two’s complement of an integer A is given by - (A + 1). ~170 => -(170 + 1) => -171. Here are a few points to note about the 32-bit signed integers used by JavaScript bitwise operators: The most significant (leftmost) bit is called the sign bit. The sign bit is always 0 for positive integers, and 1 for negative integers.
