The software industry is constantly evolving. Many languages that were at the forefront a few years ago seem obsolete or have become completely redundant at present.
As a web developer who deals daily with JS I will try to clarify why I think this language is so successful.
It’s pretty much everywhere
Fashions move the masses and in the end, if the big companies bet on a technology they get the rest of humanity to follow in their footsteps. I’m sure that if companies like Apple, Google or Facebook opted for Cobol, they would end up getting this old language resurrected from their grave. (I am still surprised when I read that there are banks that are programmed in this primitive language — Of course, I am sure that the one who continues programming in Cobol is right now swimming among gold coins).
It’s Open Source
And one of the great advantages of Open Source projects is the great community behind them. This point could be linked to the previous because you can find any problem solver in Google or StackOverflow for sort out your problem. Or if you newbie you can quickly ask any question.
