Core Characteristics
- Uses
.res
file extension with emphasis on strong typing
- Takes a JavaScript subset approach, unlike TypeScript's superset philosophy
Advantages over TypeScript
- Compiler differences:
- TypeScript's compiler grows increasingly complex due to its superset approachTypeScript's compiler grows increasingly complex due to its superset approach
