It depends on the app. If it can be started using HTML and JavaScript then there's no reason to learn a framework first and by 'first' I mean second because learning the framework comes after choosing the framework and by 'second' I mean third because choosing a framework comes after researching frameworks and getting a handle on the confusion.

And a beginner is by definition not in a position to carry out informed research or make an expert decision. So just start.

Good luck.
