Ask HN: Where's the best place or best way to learn JavaScript syntax?

I did computer science at university but due to many external life pressures, couldn't keep up the pace with the programming modules. After university i went into IT support instead of coding. So I haven't had much practice but I understand fundamentals well (at least i feel).

Im trying to get myself back into coding as i often need it for work (front end only).

I find i can grasp coding concepts really well but when it comes to implementation i always get it wrong on syntax.

Today i had 6 lines of code and even with the help of JSHint, it took me 1hr to debug. My syntax was wrong.

I've read a 2 books on js already but still the JS syntax rules don't seem to be sticking.

I realise much of this comes down to practice but i'd love if there was something to help me up my game?
