Additional Assignment (+=)

This operator adds the value of the right operand to a variable and assigns the result to the left operand.

Multiplication Assignment (*=)

This operator multiplies left and right operand values and assigns the result to the left operand.


var x = 10;
x *= 5;
//OUTPUT: X will be 50

Division Operator (/=)

This operator divide left operand value by right operand value and assign the result to the left operand.


var x = 10;
x /= 5;
//OUTPUT: X will be 2

Reminder Operator (%=)

The remainder assignment operator divides a left operand by the value of the right operand and assigns the remainder to the left operand.

x %= 5;
//OUTPUT: X will be 0
