This article will explain in detail how JavaScript can be quickly exponentiated, Xiaobian thinks it is quite practical, so share it with you as a reference, I hope you can gain something after reading this article.

Fast exponentiation

Starting with ES7, we can use the power operator ** as shorthand for exponentiation, which is faster than Math.pow(2, 3). This is a very simple and practical point, but most tutorials don't specifically cover it.

console.log(2 ** 3); // Result: 8

This should not be confused with the ^sign, which is usually used to represent exponents, but in JavaScript is the bitwise XOR operator.

Before ES7, shorthand for powers relied primarily on the bit-left shift operator.
