When Google introduced the beta of Angular 2 earlier this week, it did so with the help of more than 1,300 contributors to the Angular open-source project, not the least of which was Microsoft. Indeed, Google wrote Angular 2 in TypeScript—Microsoft's superset of JavaScript..."TypeScript brings a lot of productivity features that server-side developers love to the JavaScript world, such as type checking and API auto-completion," said TJ VanToll, a senior developer advocate at Telerik. "We at Telerik provide first-class TypeScript support in NativeScript, and having the same TypeScript support in Angular 2 makes it that much easier for us to integrate the two frameworks. The best thing is neither Angular 2 nor NativeScript depends on TypeScript, which means developers that want to use TypeScript get the benefits they're looking for, and those that don't aren't forced to use the language."
