What is interpolation in Angular?

Angular is a convenient alternative to property binding. It is a special syntax that Angular converts into property binding. Interpolation is represented by double curly braces ({{}}). The text between the curly braces is often the name of a component property. Angular replaces that name with the string value of the corresponding component property.

In Angular, interpolation is a way to bind data from your component’s TypeScript code to your HTML template. It allows you to dynamically render data in the view by embedding expressions within double curly braces {{ }}. When Angular encounters such expressions in the HTML template, it evaluates them and replaces them with the corresponding property values from the component.

For example, if you have a component with a property named name set to "John", you can display this property in your template using interpolation like so:

html
<p>Hello, {{ name }}!</p>

When Angular renders this component, it will replace {{ name }} with the value of the name property, resulting in:

html
<p>Hello, John!</p>

Interpolation is a powerful feature in Angular as it enables dynamic rendering of data and facilitates the interaction between the component class and its template.
