Lambdas are actually so hipster that they were cool before we even had programming languages: https://en.wikipedia.org/wiki/Lambda_calculus

As far as I know, Lisp was the first language to actually implement the idea. I actually struggle to think of any language concepts that were introduced by Javascript.

I also tend to disagree with the overall sentiment that new languages aren't a good way to influence programming. Haskell, for example, is quite a departure from a language like C. I don't think we would've ended up with the great, proven options we have today if everything was just incremental changes on some base. Sometimes you need to rethink things from scratch. It's part of the reason we don't have one language that fits perfectly for all problem sets.
