The objective for this milestone was to have enough of a language to support a standard library.

But that's not all. I got carried away and also built the packages for a simple Elm-like framework 🕺

✔️ https://github.com/ditto-lang/js-exception
✔️ https://github.com/ditto-lang/js-unknown
✔️ https://github.com/ditto-lang/js-task
✨ https://github.com/ditto-lang/vdom

And that framework can produce a working TodoMVC example!

• if then else expressions #21
• match expressions #22
• do expressions #35
• |> operator #41
• _unused names #45

Full Changelog: 0.0.1...0.0.2

0.0.1

First public release, and coincides with the compiler source code being made public.

Most of the important functionality exists but is very rudimentary.

Namely, there is:

• A parser, typechecker, and linter for an initial module syntax. The expression language is very limited at this stage.
• A JavaScript code generator.
• A build system based on Ninja.
• A basic package manager, based on package sets and local package directories.
• A fairly naive code formatter.
• A language server with documentFormattingProvider and semanticTokensProvider capabilities. Which are enough to power a basic VS Code extension.
