Populating form data by using AJAX data sources are an excellent way to speed up your website. However, if you are populating multiple data sets each time you open a form, then the application can become so chatty that it actually becomes slower than pre-processing the entire thing! With HTML5 local storage options, you can seriously speed up your website. With an SPA, we often run into the “back” button resulting in us having to run a search again so the user sees the same search results they had before. Now, we can jam those search results in a local cache and bring them back up without calling the server again.
