箭头函数是否比类似的常规(匿名)函数更具性能? [英] Is an arrow function more performant than a similar regular (anonymous) function?

问题描述

根据 MDN :

箭头函数表达式在语法上是常规函数表达式的紧凑选择，尽管没有与this，arguments，super或new.target关键字的绑定.

An arrow function expression is a syntactically compact alternative to a regular function expression, although without its own bindings to the this, arguments, super, or new.target keywords.

大概，没有绑定比绑定具有更高的性能.

Presumably, not binding is more performant than binding.

推荐答案

与类似的常规(匿名)功能相比，箭头功能的性能如何?

How is an arrow function more performant than a similar regular (anonymous) function?

不是.两者都是 function 类型，并且性能差异可以忽略不计.

It isn't. Both are function type, and the performance difference is negligible.
