A Brief Overview of Data Binding In Angular Framework

Data Binding in Angular:

Data Binding is nothing but the automatic synchronization between the model and view. When data in a model changes the view automatically changes itself according to it and vice-versa or we can also say how model and view communicate with each other.

Types of Data Binding in Angular:

1.String Interpolation:

String interpolation is a form of data-binding in which text is written between two curly braces mostly written the name of a component property.Angular replaces that name with the string value.String interpolation is a one-way data-binding technique that is used to transfer the data from a TS code to an HTML component.

For example: {{string}} in this way data is written between two curly braces and it's value is updated in view.

2.Property Binding:

Property Binding is a form of data-binding in which data is written between two square brackets and is defined as updating the value of a certain value in component and displaying it in view.It is a one-way mechanism,thus it allows us to change the value whenever we want to change but only at component level.

For example: [disable] in this data is written between square brackets and updates value according to it.

3.Event Binding:

Event Binding is a form of data-binding in which data is written between banana brackets and is defined as updating the value of a certain variable from the view to the model or we can say component.It is also a one-way data-binding but here data flows from view to model.

For example:(click) in this way data is written between banana brackets and calls events.

4.Two-way Data-Binding:

Two-way Data-Binding is a form of data-binding in which data is written between combination of banana brackets and square brackets and is continuous synchronization of data from view to model and model to view.It is two-way data-binding where data flows from view to model and model to view i.e. changes made in components data should sync to view and should immediately update the model in to the corresponding component with view data.

For example:[(ngModel)] in this way data is written between a combination of banana brackets and square brackets and it updates according to change in view to model and vice-versa.
