In what niche does your favorite programming language surpass all competition?

And why? What makes them special? How do they make the job so much easier than everything else?

Some examples include but aren't limited to (not necessarily my opinion):

- Web Programming: Python(Django), Ruby/Rails

- REST Api's: Haskell(Servant), Python

- Machine Learning: Python

- Embedded Software: C, Rust

- Domain-specific languages: Haskell, Ruby, Racket, Lisp

- Data Science: Scala (spark), Python, R, Julia

- Game Programming: C# (Unity), C++
