Introduction of Angular for Beginner

Angular is an open-source JavaScript framework for building web applications. It uses TypeScript, a superset of JavaScript, to create scalable and robust applications. In this article, we will provide an introduction to Angular 14 and Typescript and provide example code to help you get started.

What is Angular 14?

Angular 14 is the latest version of the Angular framework. It is a complete rewrite of AngularJS, the original version of Angular. Angular 14 provides a set of powerful features that enable developers to create dynamic and responsive web applications.

*What is TypeScript ? *
TypeScript is a superset of JavaScript that provides optional static typing, class-based object-oriented programming, and other features not present in JavaScript. TypeScript compiles to plain JavaScript, so it can be used with any browser or JavaScript runtime.

*Example Code *

To get started with Angular 14 and TypeScript, you will need to have Node.js and Angular CLI installed on your machine. Once you have those installed, follow these steps:

Create a new Angular project:

ng new my-app

Navigate to the project directory:

cd my-app
Create a new component:

ng generate component my-component

Open the ** my-component.component.ts ** file in your code editor and add the following code:

import { Component } from '@angular/core';

@Component({
  selector: 'app-my-component',
  template: `
    <h1>Hello, {{ name }}!</h1>
  `,
})
export class MyComponent {
  name = 'Angular';
}

Open the app.component.html file in your code editor and add the following code:

<app-my-component></app-my-component>

Start the Angular development server:

ng serve - o

Open your browser and navigate to http://localhost:4200. You should see the text "Hello, Angular!" displayed on the screen.

Conclusion

Angular 14 and TypeScript provide powerful tools for building modern web applications. With Angular CLI, you can quickly generate new projects, components, and other Angular artifacts. TypeScript's static typing and class-based object-oriented programming make it easier to write maintainable and scalable code. We hope this introduction and example code will help you get started with Angular 14 and TypeScript.
