You're incorrect in assuming that I've only/first learnt JS. But its sort of a trend for people to look down on JS programmers, since its considered a "low-status" language ;)
And I'm well aware that the direct inspiration for many of ES6's features is probably Python (and now C# with async/await, which in turn flowed there from F#)
I'm assuming some cross-borrowing is happening here due to developments on the TypeScript team, and due to much higher similarities of the specifics with TypeScript. After all, F# has been around for quite a while, yet we're only seeing this development now - so if F# is the inspiration, why did it not happen much earlier?
Disagree strongly. I don't think looking down on JS programmers is a trend really, it's been happening for a long time now. If anything, that era has been fading with the legitimacy that runtimes like Node and adoption by high-profile companies bring to the JS ecosystem.
As for JS itself, ES6 is a great step in the right direction, and I like it a lot, though I prefer Typescript for pretty much anything when I can use it.
Also - I didn't say that you learned it first or only, just that I see a lot of praise for 'JS features' being adopted by other languages from people who very obviously don't know any better - and this only in the last 3 or so years. So I think it's a trend.
It didn't happen much earlier because the Microsoft languages team is very deliberate and careful about rolling out new features. They have to be. There are something like 1.5 billion machines running some sort of Windows, and (I don't know) on the order of 1/2 - 1 million developers who work with MS languages and tools. Lots of backward compatibility to think about. At this scale even five 9s quality ends up breaking things.
