C-Rodg / buttonConstraint.swift

Created May 16, 2018 23:43

A sample of programmatically assign constraints to a UIButton in Swift.

	import UIKit

	class ViewController: UIViewController {

	struct LayoutProperties {
	static let sideSpacing: CGFloat = 20
	static let cornerRadius: CGFloat = 8
	static let buttonHeight: CGFloat = 60
	}

C-Rodg / Shuffle.js

Last active May 14, 2018 23:29

The Fisher-Yates (Knuth) Shuffle implemented in Javascript.

	const shuffle = (arr) => {
	let currentIndex = arr.length;
	let tempValue, randomIndex;

	while (0 !== currentIndex) {
	randomIndex = Math.floor(Math.random() * currentIndex);
	currentIndex -= 1;
	tempValue = arr[currentIndex];
	arr[currentIndex] = arr[randomIndex];
	arr[randomIndex] = tempValue;

C-Rodg / DFSgenerators.js

Created March 25, 2018 06:00

Depth-first searching of a tree using generators.

	class Tree {
	constructor(value = null, children = []) {
	this.value = value;
	this.children = children;
	}

	*printValues() {
	yield this.value;
	for(let child of this.children) {
	yield* child.printValues;

C-Rodg / StringToBytesToBase64.js

Created November 1, 2017 23:03

Convert a string to a byte array and then encode with Base64. Useful for putting complex data structures in XML.

	const convertToBytes = (str) => {
	return new TextEncoder('utf-8').encode(str);
	};

	const dataString = 'TT12345,1:49:52 PM,10/15/13';

	// ODQsODQsNDksNTAsNTEsNTIsNTMsNDQsNDksNTgsNTIsNTcsNTgsNTMsNTAsMzIsODAsNzcsNDQsNDksNDgsNDcsNDksNTMsNDcsNDksNTE=
	btoa(convertToBytes(dataString));

C-Rodg / ColorHexToRGB.js

Created October 31, 2017 22:24

A quick script using a bitwise operator to convert a color hex string into RGB.

C-Rodg / compareObjectOrArray.js

Last active October 17, 2017 15:58

A function to fully compare objects and arrays.

	const isEqual = (value, other) => {
	// Tests - same object type, same length, same items
	const type = Object.prototype.toString.call(value);

	if (type !== Object.prototype.toString.call(other)) {
	return false;
	}

	if (['[object Array]', '[object Object]'].indexOf(type) < 0) {
	return false;

C-Rodg / doOnLoad.js

Created October 13, 2017 21:24

A quick snippet using Javascript's requestAnimationFrame to determine when the document is ready or a library is loaded.

	const ready = () => {

	// Example of checking if library is available
	if ('jQuery' in window) {
	return;
	}

	// Example of checking if document is loaded
	if (document.body) {
	// Do code here...

C-Rodg / AsyncSyncPatterns.js

Created October 10, 2017 22:54

Example of doing a typically async action as synchronous with reduce() or async/await.

	const itemIds = [1,2,3,4,5,6];

	// Using reduce
	itemIds.reduce((promise, id) => {
	return promise.then(_ => api.deleteItem(id));
	}, Promise.resolve());

	// Using Async/Await
	itemIds.forEach(async (item) => {
	await api.deleteItem(item);

C-Rodg / MicroLibrary.js

Last active October 9, 2017 17:46

A small micro-library that shows how libraries like jQuery are made.

	const get = (selector, context) => {
	// Select the items to manipulate
	const GetNodes = function() {
	this.nodes = context ? context.querySelectorAll(selector) : document.querySelectorAll(selector);
	};

	// Add new class to nodes
	GetNodes.prototype.addClass = function(className) {
	for (let i = 0, j = this.nodes.length; i < j; i++) {
	this.nodes[i].classList.add(className);
