JavaScript Assignment Operators - Assignment Operators in JavaScript


JavaScript Assignment Operators

  • Assignment operators assign values to JavaScript variables.
Operator Example Same As
= x = y x *= y
+= x += y x = x + y
-= x -= y x = x - y
*= x *= y x = x * y
/= x /= y x = x / y
%= x %= y x = x % y
**= x **= y x = x ** y

Shift Assignment Operators

Operator Example Same As
<<= x <<= y x = x << y
>>= x >>= y x = x >> y
>>>= x >>>= y x = x >>> y

Bitwise Assignment Operators

Operator Example Same As
&= x &= y x = x & y
^= x ^= y x = x ^ y
|= x |= y x = x | y

Logical Assignment Operators

Operator Example Same As
&&= x &&= y x = x && (x = y)
||= x ||= y x = x || (x = y)
??= x ??= y x = x ?? (x = y)
