AngularJS has complete support for unit testing to help reduce quality assurance (QA) time. Google’s AngularJS is an all-inclusive JavaScript model-view-controller (MVC) framework that makes it very easy to quickly build applications that run well on any desktop or mobile platform. This is where architectural patterns such as Model View Controller (MVC) and frameworks such as AngularJS come into the picture.

And so we end up with spaghetti code that is difficult to maintain and test. jQuery indeed is great framework to make coding easy, but it lacks any structural guidance that can help us when the code base grows. After some time, you have 100+ JS files or even more in project – which all are referring to each other with no design enforcement. If you have worked on considerably big project which uses jQuery in UI components, then you can easily relate that over a period of time – code maintenance become sort of hell. jQuery was most noticeable framework in that list – and it is probably still the best and most easy choice for UI development. This made for a much more coherent user experience because the user could perform a task that required a remote call and still interact with the application as the call was being made and processed.Īt this time-period only, most JS frameworks came into picture such as jQuery, prototype etc. This model was in use until Microsoft introduced XMLHttpRequest which enabled the developers to make asynchronous calls to the server without actually having to refresh the page, and use the server response to partially refresh the page. form submit or button click – a fresh request goes to server and then whole new page returned from server to render response in browser. Flow was like – first a webpage was rendered in browser – then user does any interaction in webpage e.g. When initially websites were built, they worked purely on complete request-response model.
