Why is it hard to find a course on the latest version of Javascript?

Question

When I was looking for a Python course, teachers or instructors (at least two of them) told on their videos or articles us to focus on Python 3 (no Python 2). Now I'm looking for a JavaScript course, but I don't see teachers/instructors telling us to learn the latest Javascript version. Is there any reason why it happens? As a beginner, it's difficult to tell if things are outdated...

Answer 1

the latest version of Javascript is ES8.
But it's not yet popular, so I'll suggest you learn ES6, that's currently the latest JS version

Answer 2

Yahiko Thanks for your answer. Do you recommend a good ES6 course? I did the SL ES6 course, but I didn't like it as it's not as good as the SL Javascript course..
Meanwhile, I'm copying and studying the code samples from the Challenge section. I'm a kind of slow pace...
