JavaScript Assignment Operators

Assignment operators assign values to JavaScript variables.

OperatorExampleSame As=x = yx = y+=x += yx = x + y-=x -= yx = x - y*=x *= yx = x * y/=x /= yx = x / y%=x %= yx = x % y<<=x <<= yx = x << y>>=x >>= yx = x >> y>>>=x >>>= yx = x >>> y&=x &= yx = x & y^=x ^= yx = x ^ y|=x |= yx = x | y**=x **= yx = x ** y

The **= operator is an experimental part of the ECMAScript 2016 proposal (ES7). It is not stable across browsers. Do not use it.
