Best way to get into advanced JavaScript development for a PHP developer?
I've been developing things in PHP from last 4 years and now want to move into Javascript. Although, I've a basic understanding for things and can call myself an intermediate in it but with all things launched in last few years I feel quite left behind.
Specifically, I want to get into ES6 and related things, probably typescript. I'm not very clear where to start. Can anybody guide me or tell me what should be the first thing I should learn?
