TypeScript transpiles into some target JS version (ES5, ES6, ES2016, ES.Next). It is a different language but it gets executed as JS.

I think, that he was trying to say, Typescript feels like C#, so why not use the more performant option, if you use something similar but slower anyway.

  How many platforms does C# run on, with runtimes available under which licenses, again? EDIT: Not defending Slack's choice of JS, or the consequences of that choice on its memory footprint, CPU utilization, or excess consumption of my battery in any way, but it's not purely a matter of "which one is the most efficient/performant/whatever?".

      Thank you. Are those runtimes all bytecode compatible? Or is that another layer of developer cognitive burden that the more efficient/performant/whatever choice entails, atop the whole "having a good way to write cross-platform applications" tangle?

        Nope but few (if any) platforms will accommodate such a demand. Xamarin will produce different bytecode from mono, for example.

  I don't know if TypeScript is the culprit here. Just look what Microsoft pulls off with VSCode.

    I didn't look into the JS TypeScript compiles to, but I saw some output from Reason/OCaml and it looked much more streamlined for performance than what I would write in JavaScript myself. Much more use of integers than strings etc. So I could imagine that compile-to-javascript languages could get you much faster apps than traditional JS.
