That's life, some languages are better at different things; expecting any language to be all things to all problems is what eventually leaves you feeling like it's all hopeless I expect.

bash is good, for chaining small utilities together.

python is good, for single-threaded problems which don't hurt performance

go is good, if you don't want to manage memory and need easy concurrency, strong typing/etc

rust is good if you want to prevent having a footgun and low level access.

C++ is good for giving you complete control over hardware.

R is good for data science (although is being supplanted, many say, by python).

Javascript doesn't have to be the "best" if it's not competing at all things, unfortunately, as Jobs famously said: "The future is web applications" and now javascript (which, if we remember is from a spec written by 5 guys in 2 weeks) has to fit all use-cases... it's a tall order for any language.

> Atwood's Law: any application that can be written in JavaScript, will eventually be written in JavaScript. (2007)

Funny you should mention it. Excel will now support JS scripting.

That’s appropriate: it is also the case that any application that can be written as an Excel spreadsheet will be (and has probably already been) written as an Excel spreadsheet.
