[javascript] Programming in the Future right now

Question

This is more of a question for some who are doing front end web development. I know that we constantly have to think about browser compatibility mostly with CSS. The more I delve into Javascript, I see that there are some up and coming features that are not compatible with older (some would say obsolete) browsers.

My question is:
Should I just try to learn current Javascript and not worry much about older browsers?
What do you do in projects that you work on? Javascript of the past? Javascript of the future?
Do you come across comparability issues? How do you manage that?

Answer 1

Learn current javascript version. It will be easier to understand. There is something called transpilers which converts javascript to older version. I used babel transpiler, but when you use modern front-end frameworks like React or Angular you can specify to which version of javascript you want to compile. So don't worry about old browsers.

Answer 2

yes

Answer 3

@Vladi thank you. By "current javascript version" you mean ES6?
