<p style="text-align: justify;">As mentioned above, there is a huge library that comes along with the ext and as a developer you will not have to source any of the components externally or for that matter write a code for it. Ext has been built on the basic concepts of MVC and MVVM which makes it easy for the developers to learn working around it. This saves the overall time and the productivity of the people working on the project.</p>
