zeusdeux / Conversion: RGB to Hex and vice versa
Last active December 12, 2015 00:59
This gist adds two methods HexToRGB() and RGBToHex() to String and Array prototypes in JavaScript.
String.prototype.hexToRGB = function(){
if (this[0] === "#" && this.length === 7){
return String.prototype.hexToRGB.call(this.slice(1));
}
if (!/^[a-fA-F\d]{6}$/.test(this) || this.length > 6){
throw new SyntaxError("String is not a valid hex number");
}
var str = "(";
for (var i=0; i<=this.length-2; i+=2){
str+=(parseInt(this.substr(i,2),16));

zeusdeux / toAndFromBase62ToInt.js
Last active December 15, 2015 08:19
This gist has two methods that convert between integer and its base 62 equivalent.
function toBase62(number, arr){
var list = [0,1,2,3,4,5,6,7,8,9,'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'];
if(!arguments.length)
throw new SyntaxError("toBase62: Invalid syntax. Use toBase62(number[, Array])");
number = parseInt(arguments[0], 10);
if(isNaN(number))
throw new TypeError("toBase62: First parameter needs to be a valid integer number");

Things I see in production code
//not sending hex values as strings to parseInt/Float
//This is not equal to parseInt("0xff", 16)
//It's actually equal to parseInt(255, 16)
parseInt(0xff, 16);
//coercing to string and the parsing back (WHY?! T_T)
var val = 10+"";
fn(parseInt(val,10));

Functional programming toolkit for javascript
//this function composes functions like in Haskell (and most other functional languages)
//the final composed function can accept parameters dictated by the chain it creates
//you can pass it a list of functions and it shall apply them from RIGHT to LEFT (right associativeness?)
//eg., c0(fn1, fn2, fn3)(10) => return fn1(fn2(fn3(10)));
// out<---<----<----<=10
function c0(f, g) {
var last;
if (!arguments.length) return;
if (arguments.length === 1) return f;

function Circle(r){
var self = this;
var notifier = Object.getNotifier(this);
Object.defineProperty(this, "radius", {

return r;
},
set: function(newR){
if (r === newR)

var body = document.querySelector('body');
body.addEventListener('dude', function(){
console.log('dude listener');
console.log('alerting')

zeusdeux / Naive URL extraction algo
Last active August 29, 2015 14:06
Naive URL extraction (only english supported)
1) Starts with http, https? Cool. Take the whole string (assuming it's good after http|https). Stop
2) Contains http, https? Cool. Splice string from index of 'http' ('h' to be more precise) to end of string. Stop.
3) Split on '.'. foldr over the array by trying to split ever element over anything that isnt an alphabet or number. Ignore 1st element of every subsplit if the subsplit returns an array of length greater than 1. After this pass, join whole array using '.'
