JavaScript Leaders Demand Oracle Release the JavaScript Trademark
In an open letter, JavaScript community leaders urge Oracle to give up the JavaScript trademark, arguing that it has been effectively abandoned through nonuse.
@angular/core
Advanced tools
The @angular/core package is a fundamental part of Angular, a popular front-end web application platform. It provides the critical runtime parts of the Angular framework, including the component decorator, directives, dependency injection, and the core Angular APIs necessary for building dynamic single-page web applications.
Components
Components are the building blocks of Angular applications. They control a patch of screen called a view. The @Component decorator indicates that the class immediately below it is a component and provides metadata about the component.
"@Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'My Angular App'; }"
Dependency Injection
Dependency Injection (DI) is a design pattern used in Angular to make components or classes dependent on interfaces rather than concrete implementations. This improves modularity and testability.
"constructor(private myService: MyService) {}"
Directives
Directives are classes that add additional behavior to elements in your Angular applications. With Angular's built-in directives, you can manage forms, lists, styles, and what users see.
"@Directive({ selector: '[appHighlight]' }) export class HighlightDirective { constructor(el: ElementRef) { el.nativeElement.style.backgroundColor = 'yellow'; } }"
React is a popular JavaScript library for building user interfaces. It focuses on a component-based architecture similar to Angular but uses a different syntax and design philosophy. React emphasizes a one-way data flow and virtual DOM for efficient rendering.
Vue.js is a progressive JavaScript framework used for building UIs and single-page applications. It is designed from the ground up to be incrementally adoptable. Vue also focuses on the ViewModel part of the MVVM pattern and employs a reactive and composable data model.
The sources for this package are in the main Angular repo. Please file issues and pull requests against that repo.
Usage information and reference details can be found in Angular documentation.

Render default fallback with empty projectableNodes
.
When passing an empty array to projectableNodes
in the createComponent
API, the default fallback content of the ng-content
will be rendered if present. To prevent rendering the default content, pass document.createTextNode('')
as a projectableNode
.
For example:
// The first ng-content will render the default fallback content if present
createComponent(MyComponent. { projectableNodes: [[], [secondNode]] });
// To prevent projecting the default fallback content:
createComponent(MyComponent. { projectableNodes: [[document.createTextNode('')], [secondNode]] });
The timers that are used for zone coalescing and hybrid
mode scheduling (which schedules an application state synchronization
when changes happen outside the Angular zone) will now run in the zone
above Angular rather than the root zone. This will mostly affect tests
which use fakeAsync
: these timers will now be visible to fakeAsync
and can be affected by tick
or flush
.
