encode URLs

src

TL;DR

• encodeURI() will not encode ~!@#$&*()=:/,;?+' Use on entire string
• encodeURIComponent() will not encode: ~!*()' Use on tricky values. Will ruin = and &

1. get a list of e-mail addresses
2. send e-mails with personal URL from hashed e-mail address

What you want

• You want B to depend on A but
• A is not on npm (or it is - but you don't feel like publishing after each fix)

npm link

• While standing in A npm link makes a global package of A. Verify by npm ls -g --depth=0.
• A can then be used by B by doing npm link A while inside B. Verify by npm ls --depth=0.

// Problem: Callbacks are called with the window object as <this>
// Solution: Bind all functions to their object
// An implementation of http://underscorejs.org/#bindAll
// Demo -> http://codepen.io/KarlPokus/pen/Lkwqyj
function bindAll(x) {
  var wat = Object.prototype.toString;
  if (wat.call(x) === '[object Object]') {
    x = [x];
  }  
  if (wat.call(x) === '[object Array]') {
