Created May 23, 2019 21:58

Bookmarklet code for performing the same search you are already doing but on a different engine. Example: I search for 'shoes' on DuckDuckGo but I want to see if Bing or Google have more/better results.

	(function(){
	'use strict';

	var engines = {
	bing: 'https://www.bing.com/search?q=',
	duckduckgo: 'https://duckduckgo.com/?q=',
	google: 'https://www.google.com/search?q='
	};

	var engine = engines.duckduckgo; // Change to specify a different search engine

pseudosavant / jSugar.js

Last active May 24, 2024 01:07

Utility function that adds in some jQuery-like syntactic sugar

	// jQuery-like syntactic sugar. Only queries for one element. Does not loop over multiple like jQuery
	export function $(query) {
	if (typeof query === 'undefined') throw 'No query provided to $';

	var el;
	if (typeof query.nodeType === 'string') {
	el = query;
	} else if (typeof query === 'string' && query[0] === '<') {
	const container = document.createElement('div');
	container.innerHTML = query;

pseudosavant / createColorDataURI.js

Created May 9, 2019 16:40

Utility function for generating 1px x 1px PNGs data URI with a solid color. Useful for things like setting `<video>` `poster` to a color since CSS can't style that

	// Usage example: document.querySelector('video').poster = createColorDataURI(50,100,150);

	function createColorDataURI(r, g, b, a) {
	const canvas = document.createElement('canvas');
	canvas.width = 1;
	canvas.height = 1;

	const context = canvas.getContext('2d');
	const imageData = context.getImageData(0, 0, 1, 1);
	const subPixels = imageData.data;

pseudosavant / jsonWithComments.js

Last active March 13, 2018 00:45

JSON with comments POC. Example here: http://jsbin.com/favarow/

	// jshint esnext:true

	/*
	Every JSON entry is removed if the key is "_comment". "_comment" can optionally be followed
	by underscores, letters, or digits to make the key more unique (e.g. "_comments_name", "_comments_todo").
	The JSON is still valid JSON with the "_comment", and it will parse fine anywhere. It will
	just have the extra "_comment" entries.

	See example here: http://jsbin.com/favarow/

pseudosavant / string-divider.js

Last active January 26, 2022 16:58

Divide any number/string every nth characters

	const divide = (str, divider, n) => String(str)
	.split('')
	.reverse()
	.reduce((acc, cv, i) => cv + (i % n === 0 ? divider : '') + acc);

	let num = 4000000;
	divide(num, '\|', 2); // 4\|00\|00\|00
	divide(num, ',', 3); // 4,000,000
	divide(num, '-', 1); // 4-0-0-0-0-0-0
