TypeScript's number type is a lie(bluepnume.medium.com)

    Supporting operator overloading is part of the linked TS issue [1]. But I'm more curious: why did operator overloading in ES6 itself [2] die?

      Probably if nothing else, impossible to have it perform well without static typing?

    Am I incorrect in thinking this is not a TypeScript problem, but a problem most languages have, and that TypeScript is one of the few with a neat little solution?

      In most languages you could probably solve this problem with a class. But wrapping all your numbers in a class with runtime consequences, just for a bit of extra type safety, feels quite extreme.
