This folder although seems to be a common folder but it is as important as the app folder. In this folder, we define all the re-usable components like general input box, buttons, cards etc and use them throughout the template. We say it the most important folder because after declaring the component here, if we need to change something in that component in the future, we just have to apply that change in this folder and it will be reflected throughout the whole template/app saving a lot of time for us.
