The main point of frameworks&#x2F;libraries is to set coding guidelines for the team. It&#x27;s fine to go off and invent your own framework but this causes maintenance issues for the people coming in next. Most likely, there are no docs or examples for the code you just wrote (especially the framework bits). When a framework which has a community is chosen, these boring things like docs&#x2F;examples&#x2F;references&#x2F;blog posts get fixed over time. So it&#x27;s best to pick one so that the code is easier to maintain in the long run. Besides, the focus should be on the app and not the framework&#x2F;library and writing your own is just distraction.
