Comment on the myth of type safety

  The boy scout technique: fix your types when you're working on a bug or a feature, one file at a time. Also try to use unknown instead of any for more sensitive parts, it will force you to typecheck.

    The fuck the lemons technique: resign and seek an employer that didn’t fail at the most basic level of engineering management and development culture for years and years — because life is short and we’re all running out of time… always.

    When life hands you lemons, just say fuck the lemons and bail

  I kinda feel your pain. A project that I helped launch is written in Typescript technically, but the actual on-the-ground developers were averse to using type safety, so any is used everywhere. So, it becomes worst of both worlds, and the code is a mess (I don’t have authority in the project anymore, and wouldn’t touch it even if I could).

  I’m also annoyed at some level because some of the devs are pretty junior, and I fear they are going to go forward thinking Typescript or type safety in general is bad, which hurts my type-safety-loving-soul

    In theory I’m a fan of the inferred but static typing systems that most modern languages use (kotlin, rust, TS, etc.) where most local variable types can be inferred and only return types/object fields/parameters need explicit types.

    I just despise typescript because it feels more like someone put a bandaid over JavaScript and all of its oddities instead of making a properly fleshed out language, and allowing the option for an ‘any’ type to be used freely by default emphasizes that.

      Based on your description it sounds like you haven’t given it a fair shake. I’ll take TS over JS any day, at least there is room for improvement. I will say however I personally haven’t been unlucky enough to run into projects that abuse the any type. The worst I’ve run into is a JS library with no typings I have to manually type.

        I imagine what they mean is e.g. that TypeScript can tell you something is a Date, but it doesn’t attempt to fix some of the confusing, quirky behaviour with that: developer.mozilla.org/en-US/docs/Web/…/Date#inter…

        So, yes, it’s generally better than JS, but it doesn’t actually make it good/attractive, if you’re used to the sanity of backend languages. It very much feels like lipstick on a pig.

      TypeScript is JavaScript and not in the literal it’s compiled to JS sense but in the think of TS as a linter not a language sense.

    One file at a time. Make strong pre-commit eslint rules (that way you don’t impact existing code), eventually update tsconfig. You’ll get there :)

  Print the code out and burn it
