I wouldn't necessarily say that JS is easier to learn than those other languages, but I think it's easier to be productive in it.
If you use one of those other languages with the web, people are going to want you to use Javascript anyhow. So you have to learn both, unless you only do very, very basic things.
If you use one of those languages without doing web-stuff... Ugh. Maybe some phone apps line Swift or Java might be do-able, but I dunno about productivity for a long time.
On the other hand, it's not that hard to get good enough with Javascript to build some nice usable websites and get paid. IMO it's by far the shortest path to a programming career, and that will help get good enough to learn other languages and spread out while earning income.
