3 reasons to use a CDN

A CDN, or Content Delivery Network can improve your website’s performance while at the same time save you bandwidth. Here’s 3 reasons to use a CDN.

Introducing MemoryStorage

Web Storage API

HTML5 gave us this beautiful thing: consistent cross-browser local storage of ‘vast amounts’ of data on the visitor’s computer in the form of the Web Storage API.
