Can you tell me why Microsoft and google trying to write either supersets or a javascript clone to replace javascript? Because that language is an issue itself. I don't know one good programmer who is saying that you need javascript to make real money or that language is awesome. This language is a bug nothing else.
Long time javascript programmers are the loser (if they never learned more than javascript) they don't know how to programming an almost perfect program. That is the reason why they using javascript on Desktop. The average programmer learns just one fucking language but being a good programmer you need at least to learn 2+ languages. That you can see the performance issues in your stack. I started with PHP and javascript while this time I didn't care about performance and now I'm a c/golang programmer. When I started to study c and golang I just released how bad the whole javascript stuff is actually.
