ESX (e.g. ES5, ES6, ES10) refers to versions of JS. Every new version adds some new features. If you find a tutorial that teaches ES6, it'll still be broadly applicable to ES10, it might just turn out that there are better ways to do one or two of the things you learn. That being said, learning the "old way" will still make it much easier to learn the "new way." Answer from PPewt on reddit.com

Am I the only one who finds the ES6 part of the Javascript course complicated?

That's pretty common. The syntax in the basic javascript section is largely what we refer to as "human readable". You're now learning some of the more complex features of the language that are less verbose and abstract away parts of the process. Just keep working on it and practicing. It's normal for this to be hard.

[AskJS] How often do you use the ES6+(ES7, ES8, ES9 and ES10) syntax? Do you like it? Does it help?
All the time, as often as possible. Many of the changes are designed to reduce code size and enhance clarity, it'd be absurd not to use them. ?? ?. { ...a } ( ...a ) { } = [ ] = { a = } [ a = ] class () => .findIndex It goes on and on. Can't wait for Temporal. More on reddit.com
