Signals: Signals is a system that tracks your states throughoout an application, allowing the framework to optimize rendering updates. It is either Writable or read-only. Writable Signals: It provide an API for updating their values directly.we can create an writable signals by calling the signal function with the signals initial value: const count =signal(0); console.log('The count is :'+count()); to change the value we use .set() or .update() count.set(3) or  count.update((value)=> value +1);

Directives Directives are classes that add additional behavior to elements in your Angular applications. There are three types of directives provided by angular: 1.Attribute Directives 2.Component Directives 3.

 Angular  Angular is framework that is developed and maintained by google.It is  powerful, full-featured framework for building large-scale, structured frontend applications , especially useful in enterprise-level projects. Core Foundation  a.Components b.Services c.Data Binding d.Templates e.Routes g.Life Cycle Hooks a.Component A component is the fundamental building block of every Angular UI. Each one owns a slice of the screen and is defined by three things working together: a TypeScript class (the logic), an HTML template (the view), and CSS styles (the appearance). The decorator @Component wires them together and tells Angular where to render the component via its selector . Components communicate with each other through @Input() (data flowing in from a parent) and @Output() with EventEmitter (events flowing out to a parent). This creates a clear, predictable data flow through the component tree. Here's how the structure looks: In code: Directives: Directi...
