11) What does Cli stand for, and what does it do?
It stands for Command Line Interface and is used to create an Angular application. Additionally, it helps to create an applicationâs unit and end-to-end test.

|It works on MVS (Multiple Virtual Storage).||It works on MVP architecture.|
|AngularJS uses dynamic HTML attribute to make an easy to understand the application.||Backbone.js uses underscore templates to understand the application.|
|It has large community support.||Community support is restricted to the underscore template.|

14) Explain the linking function and its types
Link combines the directives with a scope and produces a live view. For registering DOM listeners as well as for updating the DOM, link function is responsible. After the template is cloned, it is executed.
An injector is a service locator. It is used to retrieve object instances as defined by provider, instantiate types, invoke methods, and load modules. There is a single injector per Angular application, it helps to lookup an object instance by its name.
2 What is String Interpolation in Angular?
String Interpolation is a one-way data-binding technique that outputs the data from TypeScript code to HTML view. It is denoted using double curly braces. This template expression helps display the data from the component to the view.Â
Template statements are properties or methods used in HTML for responding to user events. With these template statements, the application that you create or are working on, can have the capability to engage users through actions such as submitting forms and displaying dynamic content.
The template here is deleteHero. The method is called when the user clicks on the button.
