How TO - JavaScript Exponentiation (**)

Learn how to use JavaScript Exponentiation (**).

Exponentiation Operator

The exponentiation operator (**) raises the first operand to the power of the second operand:

let x = 5;
let z = x ** 2; // result is 25

x ** y produces the same result as Math.pow(x, y):

let x = 5;
let z = Math.pow(x,2); // result is 25

The exponentiation assignment operator (**=) raises the value of a variable to the power of the right operand.

let x = 5;
x **= 2; // result 25
