JavaScript has an exponentiation operator (**), that can call a power operator. This operator raises the first operand to the power of the second operand.
x ** yAnother way you can use is the Math pow() method.
JavaScript power operator
Simple example code.
<!DOCTYPE html>
<html>

<script >
let number = 2;
let exponent = 3;
//using the exponent operator
console.log( number ** exponent);
// using the Math library
console.log(Math.pow(number, exponent));
</script>
</body>
</html>Output:
The exponentiation assignment operator (**=) raises the value of a variable to the power of the right operand.
let x = 5;
console.log(x **= 2) //25More examples
console.log(3 ** 4); // 81
console.log(10 ** -2); // 0.01
console.log(2 ** 3 ** 2); // 512
console.log((2 ** 3) ** 2); // 64Usage with unary operators
To invert the sign of the result of an exponentiation expression:
-(2 ** 2) // -4To force the base of an exponentiation expression to be a negative number:
(-2) ** 2 // 4Do comment if you have any doubts or suggestions on this Js operator topic.
