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 applications 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 lth1gtWelcome, name !lt/h1gt
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 ltbutton disabled"isButtonDisable
d"gtClick Melt/buttongt

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 ltbutton (click)"handleButtonClick(
)"gtClick Melt/buttongt
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 _at_angular/forms in
your Angular module. For example
htmlCopy code ltinput (ngModel)"username"
type"text"gt
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.
