![What is data binding in Angular
In Angular, data binding is a powerful feature that allows you to establish a
connection between the data in your applicationâs component and the HTML
template that is rendered to the user. It enables you to effortlessly synchronize
and update data between the component and the view, providing a seamless user
experience.
Angular offers several types of data binding:
1. Interpolation ({{ }}): Interpolation allows you to bind a component
property directly into the HTML template. By enclosing the property within
double curly braces, Angular evaluates the expression and displays the
property value in the template. For example:
htmlCopy code
<h1>Welcome, {{ name }}!</h1>
1. Property binding ([ ]): Property binding enables you to bind a component
property to an HTML element's property. By using square brackets, you can
assign a value from the component to a property of an HTML element. For
example:
htmlCopy code
<button [disabled]="isButtonDisabled">Click Me</button>](https://image.slidesharecdn.com/whatisdatabindinginangular2-230712070434-706b7183/85/What-is-data-binding-in-Angular-1-320.jpg)
![1. Event binding (( )): Event binding allows you to handle events triggered by
HTML elements and bind them to methods in your component. By using
parentheses, you can specify the event you want to listen to and call a
corresponding method in your component when the event occurs. For
example:
htmlCopy code
<button (click)="handleButtonClick()">Click Me</button>
1. Two-way binding ([(ngModel)]): Two-way binding combines both property
binding and event binding, allowing changes in the component to update
the view and vice versa. It establishes a bidirectional flow of data between
the component and the template. This feature requires importing
the FormsModule from @angular/forms in your Angular module. For example:
htmlCopy code
<input [(ngModel)]="username" type="text">
These are some of the main data binding techniques in Angular. They provide a
convenient way to keep your component and template in sync, making it easier to
develop dynamic and interactive applications.](https://image.slidesharecdn.com/whatisdatabindinginangular2-230712070434-706b7183/85/What-is-data-binding-in-Angular-2-320.jpg)
