TypeScript is an open source programming language developed by Microsoft and first released in 2012. It is designed to add type safety to JavaScript while conforming as closely as possible to the syntax and semantics of the ECMAScript standard.

It is a syntactical superset of the JavaScript programming language; all valid JavaScript source code is also valid TypeScript source code, but not vice-versa. TypeScript compiles (or transpiles) to JavaScript, meaning that it can be utilized to target any JavaScript environment. It can be used to develop JavaScript for both client-side and server-side applications.

Is this demo correct? how ngZone knows when to update the view as zone.js hasn't patch someNewAsyncAPI

export class AppComponent implements OnInit {
  constructor(private ngZone: NgZone) {}
  ngOnInit() {
    // New async API is not handled by Zone, so you need to
    // use to make the asynchronous operation in the Angular zone
    // and trigger change

ES imports and exports can only be used at the top level of a module. This is illegal:

  export { container }
  namespace N { }

The current errors for these three statements are vague and, for JS, contain irrelevant terms:


(1) "An import declaration can only be used in a namespace or module."
(2) "An export declaration can

Describe the bug
In Firefox, the zoom feature uses transform styles (see storybookjs/storybook#12845) - unfortunately this breaks positioning on elements that require position: fixed when in the "Docs" view.

Normally a position: fixed element's position would correspond to the viewport but in Firefox it corresponds to the element with the transform style.

Copy some text, then on official demo, select all content (ctrl A + ctrl A) and try to paste. Nothing happens.

This is a minor bug, because a quick workaround is to delete the text prior to paste the content of the clipboard.

Steps to reproduce:

  1. Copy some text
  2. Go to
  3. Select all content, by typing ctrl A + ctrl A
  4. Try to paste
