      What happens when do this in #JavaScript? const arr = [1, 2, 3, 4, 5] arr.reverse() ...now imagine a huge code base.

      man this happens to me too when not paying attention. I really like clojure's convention of marking mutative functions with !, wish js had.

      Yes! Ruby also has this along with ? for methods that return a boolean.

      Who do we talk to to make this happen? @TC39 @babeljs @wycats

      I like it in ruby but I don't see a path in JS :/

      Thanks for the response! Can you elaborate at all? Too much of a breaking change for existing methods and code? I’m really curious.

      1. not sure if suffix ! is unambiguous. 2. existing mutating methods already don't use !

      Replying to @wycats @threepointone and

      Agree that updating existing methods to use ! would be very hard. Making it optional is kind of pointless. Your first point is interesting…

      For the first point do you mean unambiguous to humans or the compiler. Or both?

      when analyzing, remember: - ASI - unary ! operator

          Quick analysis shows we're clear of the most obvious hazards: let x = reverse!(a); is not already: let x = reverse; !(a);

          Interesting. I’m trying to think of issues with ? now. Ternary operator and maybe the new Null Propagation Operator?

          I want to try implementing this in Babel just for fun/learning. See how far I get before it all falls apart. Thanks for the discussion!
