What does the @ (at sign) mean in the latest TypeScript (presumably v1.5) example?

问题 There is a very interesting picture was posted in the official TypeScript blog. I wonder what the @ (at sign) symbol is doing there since (as far as I know) it cannot be used in JavaScript identifiers. 回答1: The big news this week is the merging of AtScript and TypeScript. The following example from the AtScript documentation... @Component() class MyApp { server:Server; @Bind('name') name:string; @Event('foo') fooFn:Function; @Inject() constructor(@parent server:Server) {} greet():string {} }

问题 Global events (window.onresize) didn't change the local variable's value. export class TestComponent implements OnInit { a: number = 0; b: number = 0; ngOnInit() { window.onresize = () => { this.a = 10; this.b = 10; }; } } 回答1: Bind to global events using host binding (this is mentioned in the API docs, deep inside the DirectiveMetadata page): @Component({ selector: 'my-app', template: `<p>Resize window and look at console log. <p>{{a}} {{b}}` }) export class AppComponent { @HostListener(

Visual Studio 2015 Enterprise with ReSharper 10 Ultimate — Cannot be properly resolved

I have Visual Studio 2015 Enterprise, version 14.0.24720.00 Update 1 as well as ReSharper 10 Ultimate, version 10.0.2 installed. I have a typescript file that is using AtScript syntax to refer to the Angular2 directive module, as its annotation. However, ReSharper is stating the following error: Symbol 'Directive' cannot be properly resolved, probably it is located in inaccessible module. Below is the full error tooltip. The application compiles and runs as expected, and the angular portions of the application also function as desired. It appears as though this is a ReSharper false negative.
