There has not been that many exciting new features in JavaScript last few years, but most recently it has changed. The FileSystem API in browser now allows website to access user’s native file system. The Observable API will finally bring Observable natively into JavaScript, which is by far the best state management solution for UI’s and handy for many other things. And most importantly, the struct API will be a huge game changer, the struct API will allow to create C-like structs in JavaScript, which will also be sharable across threads. This will enable effecting shared-memory parallel programming in JavaScript, which was not possible so far and has forced so many projects and developers pick Go or Rust, instead.
