Core Priorities

1. Lower the barrier of entry to adopting and understanding TypeScript. North star.

2. Understand the TypeScript Codebase enough to provide useful API documentation and fix bugs. Validated by having a more comprehensive set of tools for people to understand how the language and tooling works.

3. Make contributing to TypeScript easier, and reduce the amount of work maintainers need to do. Validated probably by the number of open PRs, and the number of external contributors per release.

4. Make it easier to people wanting to build tooling around TypeScript. Validated by seeing more usage of tools like the community discord, people shipping tools with TypeScript support by default etc.
