Power of a Number

Explore how to calculate the power of a number recursively in JavaScript. Understand the concept of exponents, break down the problem into smaller subproblems, and implement a recursive function with a clear base case to compute powers effectively.

What does “Power of a Number” mean?

The power (or exponent) aa, of a number xx, represents the number of times xx needs to be multiplied by itself.

xx to the power aa is the product of xx with itself aa times!

It’s written as a small number to the right and above the base number.

For example, if the base number is 22 and the exponent value is 33, we represent this as follows:

23=82^3 = 8 ...
