The *= operator is a compound assignment operator in JavaScript that multiplies a variable by a given value and assigns the result to the variable itself.

Syntax

variable *= value;

Example

Let’s say we have a variable x with an initial value of 5. If we want to multiply x by 3 and assign the result back to x, we can use the *= operator as follows:

let x = 5;
x *= 3; // Equivalent to: x = x * 3;
// Now, the value of x is 15

Usage

The *= operator is commonly used when we want to update the value of a variable by multiplying it with another value.

Conclusion

In this post, we discussed the *= operator in JavaScript, which is a convenient way to perform a multiplication operation and assignment in a single step.
