Introduction to Web Storage
Web Storage also known as DOM storage is web application technology which allows storage of data inside a web browser. It is similar to storing data in cookies but the capacity is huge, but unlike cookies no stored data is sent over to the server with each request. Web storage can store both persistent or session based data, and key value pair but only of string data type and nothing else.
This allows developers to cache/store data on the client end and save time fetching data from server or as a fail-safe to failed internet connection, an example would be Wordpress where when you compose a post the details are stored into the Web storage and in case of a browser crash or failed submit to the server Wordpress easily recovers it an shows it.
Make sure you have a web browser from the above mentioned list to try the following code sample.
