TypeScript 1.1

性能改进

🌐 Performance Improvements

1.1 版本的编译器通常比任何之前的版本快约 4 倍。请参阅 这篇博客文章了解一些令人印象深刻的图表。

🌐 The 1.1 compiler is typically around 4x faster than any previous release. See this blog post for some impressive charts.

更好的模块可见性规则

🌐 Better Module Visibility Rules

TypeScript 现在只有在提供 declaration 标志时，才会严格执行模块中类型的可见性。这对于 Angular 场景非常有用，例如：

🌐 TypeScript now only strictly enforces the visibility of types in modules if the declaration flag is provided. This is very useful for Angular scenarios, for example:

ts
module MyControllers {
  interface ZooScope extends ng.IScope {
    animals: Animal[];
  }
  export class ZooController {
    // Used to be an error (cannot expose ZooScope), but now is only
    // an error when trying to generate .d.ts files
    constructor(public $scope: ZooScope) {}
    /* more code */
  }
}
