Difference between ECMAScript 2016 exponentiation operator and Math.pow()
问题 What is the benefit to using the ECMAScript 2016 exponentiation operator over the current Math.pow() ? In other words, besides reducing key strokes, what is the difference between Math.pow(2, 2) => 4 and 2 ** 2 => 4 回答1: None. As you can read in the ES7 spec, both Math.pow and the ** exponentation operator cast their arguments/operands to numbers and use the very same algorithm to determine the result. Addendum : this changed with the introduction of the BigInt type in ES2020, whose values
