Status and Roadmap

High level status

• Most of TypeScript's AOT-compatible syntax is supported
• A managed runtime takes care of memory management and GC
• Classes are more like C-structs with methods (no virtual overloads yet)
• Standard library is functional but still needs more work
• Throwing an exception terminates the entire program (needs WebAssembly/exception-handling)
• 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 (TLSF)
  • Automatic reference counting & garbage collection (PureRC)
• Get a working standard library up (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:
