Angular, developed by Google, is an open-source software engineering platform used for building user interfaces (front-end). It was developed by google developers named Misko Hevery and Adam Abrons. This framework is currently known as AngularJS and it’s first official release dates back to 2010.
AngularJS: With its first release, it’s main benefit was that it would let developers turn HTML-based documents into dynamic content. Before AngularJs came into existence, HTML and web markup languages were usually static. This means users couldn’t actively interact with HTML pages’ interfaces as the ways to build dynamic SPAs were really complex at that time.
Angular 2+: Google released Angular2 in September 2016. In this release, the Angular framework was completely re-written by the same development team to match the modern requirements of the web. This gave developers a tough time as migrating to Angular2 required too many modifications due to different syntax.
