9 What is the difference between interpolated content and the content assigned to the innerHTML property of a DOM element?
Angular interpolation happens when in our template we type some JavaScript expression inside double curly braces ‘{{ someExpression() }}’. This is used to add dynamic content to a web page. However, we can do the same by assigning some dynamic content to the innerHTML property of a DOM element. The difference between the two is that, in Angular, the compiler always escapes the interpolated content, i.e., HTML is not interpreted, and the browser displays the code as it is with brackets and symbols, rather than displaying the output of the interpreted HTML. However, in innerHTML, if the content is HTML, then it is interpreted as the HTML code.

3 What do you mean by string interpolation?
String interpolation in Angular, also known as the mustache syntax, only allows one-way data binding. It is a special syntax that makes use of double curly braces {{}} so that it can display the component data. Inside the braces are the JavaScript expressions that Angular needs to execute to retrieve the result, which can further be inserted into the HTML code. Moreover, as part of the digest cycle, these expressions are regularly updated and stored.
3 What do you mean by data binding?
Data binding is among the most important and powerful features that help in establishing communication between DOM and the component. It makes the defining process of interactive applications simple as you no longer need to panic about data pushing or pulling between the component and the template.
Listed below are the four types of data binding in Angular:
1 What is data binding in Angular?
Data binding is one of the most significant and effective elements for creating communication between the DOM and the component. It makes designing interactive apps easier by reducing the need to worry about data pushing and pulling between the component and the template.
There are Four types of Data binding in Angular:
Property Binding: One method of data binding is called property binding. In property binding, we connect a DOM elements property to a field that is a declared property in our TypeScript component code. In reality, Angular transforms string interpolation into property binding internally.
Event Binding: Using event binding, you may respond to DOM events like button clicks and mouse movements. When a DOM event (such as a click, change, or keyup) occurs, the components designated method is called.
String Interpolation: In order to export data from TypeScript code to an HTML template( view ), String Interpolation is a one way data binding approach. The data from the component is shown to the view using the template expression enclosed in double curly braces. The value of a component property is added by using string interpolation.
