> simple functionality to an existing web app (like form validation)

If all you are doing is adding a simple form validation to an existing web app, then you only need few lines of plain JS. You don't have to use vue either.

Same happens when one learns touch typing using a tool where words are random or not valid words at all(like keybr).

When using such tool, at some point where there is no need to focus on keys or words, mind will drift into thinking something else.
