If you like the functional style of programming, though, you’ll find a lot more facilities for it in Rust, because Rust has a lot more facilities than Go in general.

Another option is the use the functional library Ramda, while the syntax may be a bit different from the Ruby and Pure JS version, I find it to be more declarive: list = [null, "say", "kenglish", "co", null] R.reject(R.isNil, list) // return new array [ 'say', 'kenglish', 'co' ]

multi-paradigm: functional, imperative

But now, you can do the same thing in functional style!
