Status and Roadmap

Current state of development is tracked in GitHub projects.

High level status

• Most of TypeScript's AOT-compatible syntax is supported
• Manual memory management is in but GC remains to do
• Classes are still wonky when it comes to the details
• Standard library is very basic and needs a lot of work
• No exception support yet, waiting for WebAssembly/exception-handling to land
• We need more tests (pretty sure this will remain here)

High level goals

• Get a memory manager and GC combo up and running
  • Memory manager
  • GC
• Get a standard library up that "just works" (where AOT-compatible)
• Improve linking, e.g. with C, based on what's supported by common tools
• Compile the AssemblyScript compiler to WebAssembly using itself
• Provide tools to automatically generate glue code and definitions

And, of course, keep up with the state of WebAssembly, most notably at this point:
