如何在Edge中执行名称为字符串的JavaScript函数

Question

 function test(arg) { console.log("hello! " + arg); return true; } window["test"]("I AM"); 

In this code snippet I execute a function by its name as a string. It works in most browsers except Microsoft Edge. How can I execute a function in Edge if I only know its name as a string? I don't want to use eval().

If you define your function straight to the window object then you can call it just with the string.

window.test=(args)=>{console.log("hello! " + arg)}

window["test"]("My first stack overflow answer")

will return "hello! My first stack overflow answer"
