Website Front-end

Hello Friends,
Being an Entrepreneur i don’t have deep knowledge about the frameworks. Now planning to go online.
There is a query do you prefer writing your website’s front-end in complete CSS and js or you like to use other framework such as vue or react?
Also, being a startup owner i don’t have much to invest please keep that in mind and suggest the best in budget solution.

A framework will save you so much time and money in the long run. Vue and React are both great options
