This is still a work in progress and is not yet at full feature parity with TypeScript. Bugs may exist. Please check this list carefully before logging a new issue or assuming an intentional change.

Status overview:

* Program creation (read `lib`, `target`, `reference`, `import`, `files`, `include`, and `exclude`): **done**. You should see the *same files*, with modules resolved to the *same locations*, as in a TypeScript 5.8 (TS5.8) invocation
* Not all resolution modes are supported yet
* Parsing/scanning (read source text and determine syntax shape): **done**. You should see the exact same *syntax errors* as in a TS5.8 invocation
* Commandline and `tsconfig.json` parsing: **mostly done**. Note that the entry point is slightly different (for now)
* Type resolution (resolve computed types to a concrete internal representation): **done**. You should see the same types as in TS5.8
* Type checking (check for problems in functions, classes, and statements): **done**. You should see the same errors, in the same locations, with the same messages, as TS 5.8
* Types printback in errors may display slightly differently; this is in progress
* JavaScript-specific inference and JS Doc: **not ready**
* JSX: **done**
* Declaration emit: **not ready**. Coming soon!
* Emit (JS output): **in progress**. `target: esnext` (minimal downleveling) is well-supported but other targets may have gaps
* Watch mode: **prototype** (watches the correct files and rebuilds, but doesn't do incremental rechecking)
* Build mode / project references: **not ready**
* Incremental build: **not ready**
* Language service (LSP): **prototype** only, expect minimal functionality (errors, hover, go to def). More features soon!
* API: **not ready**
