How does SPA work?
A single-page application (SPA) is a web application or website that interacts with the user by dynamically rewriting the current web page with new data from the web server, instead of the default method of loading entire new pages. The goal is faster transitions that make the website feel more like a native app. SPA is just an abbreviation of single page application and only means a web app that doesn’t do full page reloads, it doesn’t require the use of any specific framework, so Gmail definitely qualifies and it used it from version one.
