There are multiple to compute exponents with JavaScript.
The newest way is the exponentiation operator **, available with ES2016 or higher.
For example, we can do this:
const a = 2 ** 3; // 8
It is right associative, so a ** b ** c is equal to a ** (b ** c). This works with all exponents.
For example:
const a = 2 ** (3 ** 4);
const b = 2 ** 3 ** 4;
a == b // true, both are 2.4178516392292583e+24
Detail browser compatibility is available at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators#Browser_compatibility
We can also use the Math.pow function, like this:
const a = Math.pow(2,3) // 8
It takes 2 arguments, the first is the base and the second is the exponent. Math.pow works with all exponents.
Math.pow is compatible with all recent browsers.
