Web1. Bitwise Left Shift. This is a binary operator denoted by the symbol “<<”. This operator will shift the rightmost bits of the first argument to their left by the value of the second argument times. The bits shifted from the right are replaced by 0 in the rightmost part for each shift operation performed. 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.

Web2 days ago · The following operators may be used with BigInt values or object-wrapped BigInt values: + * - % ** Bitwise operators are supported as well, except >>> (zero-fill right shift), as every BigInt value is signed. Also unsupported is the unary operator (+), in order to not break asm.js.
