nolanerckboyzoid if im doing light enhancement, ill just use vanilla JS. if im building something a bit more robust (ajax search to table of results with sorting etc), vue provides a good set of tools to make that development easier. what jquery did well, DOM manipulation and ajax, isnt as needed
nolanerckboyzoid an example of where Vue shines - binding data in your DOM. also templating. both things jQuery _can_ do, but Vue has it baked in (better imo).
