This is the best localStorage polyfill in the world
// I mean, seriously, localStorage is supported even by your mum. How about instead of
// casing the feature out, you give users in-memory (stale) storage instead?
// If they close your application, they deserve to lose data anyway.
// if (!('localStorage' in window)) {
if (!Modernizr.localstorage) {
window.localStorage = {
_data : {},
setItem : function(id, val) { return this._data[id] = String(val); },
getItem : function(id) { return this._data.hasOwnProperty(id) ? this._data[id] : undefined; },

Rate limiting function calls with JavaScript and Underscore.js
/* Extend the Underscore object with the following methods */
// Rate limit ensures a function is never called more than every [rate]ms
// Unlike underscore's _.throttle function, function calls are queued so that
// requests are never lost and simply deferred until some other time
//
// Parameters
// * func - function to rate limit
// * rate - minimum time to wait between function calls
// * async - if async is true, we won't wait (rate) for the function to complete before queueing the next request
