I had a few of scripts I want to load in my userscript before executing it. After some head scratching and messing around with Promises it turns out it's quite easy. This way there's no need to require a larger module loader and other dependencies, which can be a pain to work with when writing userscripts.

(function load(scripts) {
    // Wait for DOMContentLoaded/window.onload
    if (document.readyState !== "interactive" && document.readyState !== "complete") {
        document.addEventListener("DOMContentLoaded", load.bind(null, scripts));
        return;
    }

This is a shim for Element.prototype.insertAdjacentElement, which is supported all major browsers except Firefox.

Example: https://jsfiddle.net/kafene/s6Lweg5k/

if ("undefined" === typeof (Element.prototype.insertAdjacentElement)) {
    Object.defineProperty(Element.prototype, "insertAdjacentElement", {
        enumerable: false,
        writable: true,
        configurable: true,

So I found out something sad: the variadics RFC implementation was altered so that ...$arg can only come last.

And since we can't pass a non-variable default value by reference, it can go first, just kind of confusing looking, unfortunately.

<?php

function coalesce($default, &amp;...$args) {
