💎Ruby tip💎 Did you know that concatenating strings together ("a" << "b") is a lot more performant than adding them to each other ("a" + "b") or using interpolation ("#{a}#{b}")? Especially with the recent optimizations from @_byroot and others. #ruby #rails #rubyonrails

@websebdev @_byroot Could all be O(1) if we added ropes from TruffleRuby to MRI,

@websebdev @_byroot Good you rewrote the tweet, wanted to comment what you actually mean. 👍

@websebdev @_byroot Mmm I would advise something different! You better freeze all your string literals to save tons of memory. (by adding # frozen_string_literal: true at the beginning of every ruby file) And doing so, will make your strings immutable, so you can't do 'a' << 'b' anymore.

@websebdev @_byroot a >> b

@websebdev @_byroot How about joining an array into a string? (May check that myself)
