   es6_maps, new Elixir syntax feature via runtime compiler hacking▲71

   Hi HN! I thought you might enjoy this even if you don't know much about Elixir. `es6_maps` is a small library that introduces a "shorthand" map creation syntax, similar to shorthand object construction in JavaScript/TypeScript. For those unfamiliar with Elixir, the most interesting aspect might be how it achieves this. `es6_maps` takes advantage of BEAM (Erlang's VM) hot-reload capabilities to amend the Elixir compiler bytecode at runtime, adding functions that expand the shorthand syntax for further compilation. I think it's a nice showcase of the power you can wield (with care) when…

    ESInfer – Make JavaScript Type-Safe▲83

    Hello, folks. I'm Jiang, the author of ESInfer. I love writing Javascript because it has a prosperous ecosystem and is quick to get my hands dirty. However, sometimes it's painful when the flow is not fast to follow due to the lack of a type system. To solve this, I wrote ESInfer, a statical inference tool, to automatically type check and generate type annotations for Javascript. It works with pure Javascript without any add-ons to the language or user-space code and supports highly dynamic features, such as the modification of prototypes. It is still in the very early stage, which offers…
