davidsharp / ture.js
Created December 11, 2015 13:19
You want a true value? Sure. (Because apparently I can never spell 'true')
View ture.js
(function(){"use strict";
window.ture=!!("Sure, here's your true value");
davidsharp / if-useful.js
Created May 26, 2016 17:13
A helper 'library' for checking a variable's type, and returning the value or false, for some nice '||' chaining
View if-useful.js
//ES6? Use const {ifString} = ifUseful
//Otherwise just rename it, or crib the bits you want
//Why? So you can do stuff like -> `let foo = ifString(bar)||ifArray(bar).join('! ')||'Pretty useful!' `
const ifUseful={
ifString:function(v){return (typeof v === 'string'?v:false);},
ifArray:function(v){return (Array.isArray(v)?v:false);},
//What if you want something else? A single param gives you your own function!
ifTypeOf:function(type,v){return v?(typeof v === type?v:false):function(_v){return (typeof _v === type?_v:false);}},
davidsharp / snot.js
Created August 17, 2016 09:40
(Super WIP) Build boolean is/isNot functions, both simple and complex, quickly and (reasonably) easily
View snot.js
function snot(o,funcs,isNots=true){Object.keys(funcs).forEach((c)=>{o['is'+c]=funcs[c].bind(o)})}
Desired usage (we're not quite there yet):
var myObj = {foo:true, value:1337}
valueABigNumber:function(){return this.value>100;},
valueBiggerThan:function(someNumber){return this.value>someNumber;}

#!/usr/bin/env node
console.log('ios image moving has begun');
var fs = require('fs');
var path = require('path');
var rootdir = process.argv[2];

NPM-to-Yarn Cheatsheet, cribbed from

NPM -> Yarn


  • yarn does npm install
  • yarn add foo does npm install foo --save
  • and for global installs: yarn global add foo is the same as npm install foo --global

(this was cribbed from here, switched around a little, and will probably become out-dated quite quickly; yarn docs can be found here)

Last active November 4, 2016 15:28
promiseFor(), tidies up the messy nature of Promises with for-loops
View promiseFor.js
//promiseFor creates 'n' promises, and returns them as a promise
// This only resolves if all the promises resolve
// It takes an integer and a Promise-like function
// The promise-like function should take 3 arguments:
// - An integer, representing an index
// or a number meaningful to your function
// - The standard Promise resolve function
// - The standard Promise reject function
function promiseFor(forCount,promiseFn){
//return a promise
