Angular Databinding

Angular provides powerful data binding capabilities that allow you to establish and maintain a connection between your application's data and its user interface. Data binding in Angular can be categorized into three types: Interpolation, Property binding, and Event binding.

  1. Interpolation:

    • Interpolation is denoted by double curly braces {{}} and allows you to display dynamic values from your component's properties directly in the template.
    • You can interpolate both simple variable values and expressions within the double curly braces.
    • Example: <h1>Welcome, {{ username }}!</h1>

  2. Property Binding:

    • Property binding allows you to bind the value of an element's property to a value or expression in your component.
    • It is denoted by square brackets [] and can be used to set properties like src, href, value, etc., dynamically.
    • Example: <img [src]="imageUrl">

  3. Event Binding:

    • Event binding allows you to bind the behavior of DOM events (e.g., button clicks, mouse movements) to methods in your component.
    • It is denoted by parentheses () and triggers the associated method when the specified event occurs.
    • Example: <button (click)="submitForm()">Submit</button>

In addition to these basic data binding techniques, Angular also provides two-way data binding using the [(ngModel)] directive. Two-way data binding allows you to establish a synchronization between the data in your component and the input values entered by the user.

Example: <input [(ngModel)]="username">

By using two-way data binding, any changes made to the username property in your component will be reflected in the input field, and vice versa.

Data binding in Angular simplifies the process of managing and updating your application's data. It ensures that the user interface remains in sync with the underlying data and provides a seamless interactive experience for users.
