A major part of software development is maintenance.
For example, once you’ve created and offered your app to the visitors on Play Store, you also need to maintain it by updating it from time to time. This may include adding the latest features, bugs and fixes, and many more small and big developments and improvements. The updating process through Vue.JS development becomes insanely simple.
Backward compatibility is tried to maintain as much as the developers can. This can range in 90% between versions 1 and 2.
Also, the fact that a VueJS Web development company does not require a refractor easily. Hence, this also allows you to direct your resources on feature development instead of some basic rework.
