3 How does an Angular application work?

An Angular application is a Single Page Application, or SPA. This means that the entire application lives within a single page, and all of the resources (HTML, CSS, JavaScript, etc.) are loaded when the page is first loaded. Angular uses the Model-View-Controller, or MVC, architecture pattern to manage its data and views. The Model is the data that the application uses, the View is what the user sees, and the Controller is responsible for managing communication between the Model and the View.

When a user interacts with an Angular application, the Angular framework will automatically update the View to reflect any changes in the data. This means that Angular applications are very responsive and fast, as the user does not need to wait for the page to reload in order to see updated data.

Angular applications are also very scalable, as they can be divided into small modules that can be loaded independently of each other. This means that an Angular application can be easily extended with new functionality without having to rewrite the entire application.

Overall, Angular applications are very fast, responsive, and scalable. They are easy to develop and extend, and provide a great user experience.

The following is is an example of coding from an angular.json file:

 “build”: {

        “builder”: “@angular-devkit/build-angular:browser”,

        “options”: {

          “outputPath”: “dist/angular-starter”,

          “index”: “src/index.html”,

          “main”: “src/main.ts”,

          “polyfills”: “src/polyfills.ts”,

          “tsConfig”: “”,

          “aot”: false,

          “assets”: [




          “styles”: [






What are Templates in Angular?

Angular Templates are written with HTML that contains Angular-specific elements and attributes. In combination with the model and controllers information, these templates are further rendered to provide a dynamic view to the user.

2 What do you understand by scope in Angular?

The scope in Angular binds the HTML, i.e., the view, and the JavaScript, i.e., the controller. It as expected is an object with the available methods and properties. The scope is available for both the view and the controller. When you make a controller in Angular, you pass the $scope object as an argument.Â

What are decorators in Angular?Â

Decorators are a design pattern or functions that define how Angular features work. They are used to make prior modifications to a class, service, or filter. Angular supports four types of decorators, they are:

  • Class Decorators
  • Property Decorators
  • Method Decorators
  • Parameter Decorators
  • 4) Every tool has its downside, what are Angular 2’s disadvantages?

    The drawbacks of Angular 2 are:

    • Confusing: Since there are numerous ways of doing a task, it can be difficult, especially for newcomers, to choose the right way to perform a task.
    • Steep Learning Curve: On a related note, if you don’t know TypeScript, you better learn it, since it’s been introduced into Angular 2. Basic functions are easy, but when you move into advanced concepts, the curve gets steep.
    • It’s A Whole Different Animal: If you like and are used to Angular, you’re in for a shock, as Angular 2 represents a total redesign.
    • Slow User Interface: If you’re dealing with more than 2000 watchers, get ready for some major lag.
    • Inconsistent Documentation: Due to a fragmented community, there’s a lack of clear, well-written, consistent documentation.
