T3 is a minimal superset of TypeScript (v0.0.17) that provides a cleaner, simpler syntax while preserving TypeScript's type system. It removes required semicolons, parentheses around control flow statements, and other syntactic clutter. The package includes a CLI transpiler (t3) that converts .t3 files to .ts. Key differentiators: aims to reduce boilerplate more than TypeScript itself, focuses on readability, and uses PEG.js for grammar definition. Release cadence is irregular; this version should be considered experimental.
