Cheat sheet: JavaScript Array methods

Deriving a new Array from an existing Array:

['■','●','▲'].slice(1, 3)          ⟼ ['●','▲']
['■','●','■'].filter(x => x==='■') ⟼ ['■','■']
    ['▲','●'].map(x => x+x)        ⟼ ['▲▲','●●']
    ['▲','●'].flatMap(x => [x,x])  ⟼ ['▲','▲','●','●']

Process Priorities - easy Handling on Windows	Dr. Bastian Ebeling

Prio – Process Priority Saver

Have you ever changed the priority of a process in the Task Manager? Do you have to do it often? Do you want your database server or media player to know the priority it should work with?

	This function takes two arguments:
	element: a reference to a DOM node in the document e.g. a button.
	feedbackContent: a string of text or HTML.

	An example of usage would be:
	document.querySelector('button').addEventListener('click', function() {

	const { execSync } = require('child_process')
	const { createHash } = require('crypto')
	const invertColor = require('invert-color')

	const branchName = execSync('git rev-parse --abbrev-ref HEAD')
	const hash = createHash('sha256')
	hash.update(branchName)
	const color = '#' + hash.digest().toString('hex').substring(0, 6)
	const invertedColor = invertColor(color, true)

	// UPDATE: In 2023, you should probably stop using this! The narrow version of Safari that
	// does not support `nomodule` is probably not being used anywhere. The code below is left
	// for posterity.

	/**
	* Safari 10.1 supports modules, but does not support the `nomodule` attribute - it will
	* load <script nomodule> anyway. This snippet solve this problem, but only for script
	* tags that load external code, e.g.: <script nomodule src="nomodule.js"></script>
	*
	* Again: this will not prevent inline script, e.g.:

	const handleClick = e => {
	if (!modalEl.contains(e.target)) modalEl.hidden = true;
	};
