This site has demonstrations of a few common String Interview Questions solved with JavaScript.
Check out Free Code Camp’s Bonfires for lots of JavaScript practice problems.
Code Wars is great because I can solve problems and then see how others solved the same problem. Code Wars has been engaging and fun and I have also learned many different approaches and methods to solving coding challenges. Also it is gamified so I have many different opportunities to increase my points and my ranking 🙂
