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.

Answer 2

function toArray() {
   return arguments;
}

var myargs = toArray(1, 2, 3, 4, 5, 6);

The arguments keyword is available in every js function

Answer 3

var arr = [];
function testArray() {
    Array.prototype.push.apply(arr, arguments);
}
