Property/method value type:Number primitive
JavaScript syntax:-anOperand1 *= anOperand2
Argument list:anOperand1A value to be multiplied and then assigned into
anOperand2A multiplier value

Multiply the left operand by the right operand and assign the result to the left operand.

This is functionally equivalent to the expression:

anOperand1 = anOperand1 * anOperand2;

Although this is classified as an assignment operator it is really a compound of an assignment and a multiplicative operator.

The associativity is right to left.

Refer to the operator precedence topic for details of execution order.

The new value of anOperand1 is returned as a result of the expression.
