The Math.pow(base, exponent) function returns the base raised to the given power. Math.pow(2, 10) is 1024.

In modern JavaScript, the exponentiation operator ** gives the same result: 2 ** 10. It’s shorter and more common in new code.

The exponent can be a fraction or a negative number: a power of 0.5 is the square root, and a power of -1 is the reciprocal of the number.
