How to replace Array.from in JS?

Question

PHP

There is a simple code:

var AllEl= document.querySelectorAll('.first.class');
var My = Array.from(AllEl);

The old browser swears at the second line:

Uncaught TypeError: Object function Array() {[native code]} has no method 'from'

Here https://developer.mozilla.org/en/docs/Web/JavaScri... they write that this is from the ECMA6 standard, yes, there is a Polyfill, but I'm wondering how it's better to write in native JS what would be according to the old standard?

Answer 1

I understand that we are talking about the user table, and the columns should be: corporationname, corporationticker, user.corporationid, alliancename, allianceticker, corporation.allianceid, characterid, characterownerhash, user.id
Right? But what is compared with what further, I can’t understand something at all.

Not true. The query is joining three tables.

You don't understand relational databases. I don’t even know if it’s worth poking into the jungle without understanding the basics.

Answer 2

IE9+
var My = Array.prototype.slice.call(AllEl);
