Unlimited arguments in a JavaScript function

Question

Can a JavaScript function take unlimited arguments? Something like this:

testArray(1, 2, 3, 4, 5...);

I am trying:

var arr          


        

Answer 1

There are some legacy methods but I prefer the ES6 and newer versions, So if I wanna implement this, I wrote it like below:

const func = ...arg => console.log(arg);

Simple and cutting edge of tech.
