Migrating to TypeScript

TypeScript is a superset of ES6 and, as its name suggests, uses a type system. This can have an enormous impact on developer tools, providing richer auto-complete and static analysis.

Angular 2 was built using TypeScript, and supports decorators which provide meta information to Angular. While it is possible to use Angular 2 without these features, the syntax feels more "natural" with TypeScript's decorators.
