JavaScript is one of my favorite languages. It has the nearly unique design constraints of having multiple implementations and being unwilling to break backwards compatibility, which gives it a lot of warts that are easy to ridicule. But I think the language on the whole is very flexible, very simple, and very usable. I would recommend getting your head around closures. It’s possible to statically determine what variables exist in which scope, and so if you can nail down those rules it makes analyzing code much easier. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Clos... I would recommend a light linter. I see too much new JavaScript code using `var` written by non-JS devs in 2024. But I don’t think you need TypeScript if you’re first learning the language. Instead, revel in the dynamically-typed flexibility, and learn the error messages JS gives. There are only really 4 or 5 things that will cause JS to error, which can make debugging difficult initially, but once you learn those error messages, it makes debugging comparatively easy. |
