In JavaScript, if you want to perform power calculations, you can use the pow() method of the Math object. Math.pow() is the exponentiation function

The syntax is

Math.pow(x,y)

• x Required. base. Must be a number.​

• #y Required. Power number. Must be a number.

can return a value representing x raised to the power of y.

console.log(Math.pow(1, 0));
console.log(Math.pow(1, 1));
console.log(Math.pow(1, 10));
console.log(Math.pow(3, 3));
console.log(Math.pow(-3, 3));
console.log(Math.pow(2, 4));

Note: If the result is an imaginary or negative number, this method will return NaN. If a floating point overflow occurs due to an exponent that is too large, this method returns Infinity.
