React vs. Angular: Which Career Option is More Promising in 2024?

Angular vs React - An Overview

Two of the most widely used JavaScript tools for front-end development are Angular and React. Both of them are strong, have lots of support, and are actively being cultivated in their respective communities. In this article, we'll compare Angular and React in-depth to explore how they match and differ in several important areas.

What Is Angular?

Angular, developed and maintained by Google, is a comprehensive and full-fledged front-end web application framework. Released in 2010, it has undergone significant changes over the years, with the latest version being Angular 12 at the time of writing.

Angular is a TypeScript-based framework that follows the MVC (Model-View-Controller) architecture. Developers use HTML as a template language and HTML syntaxes for building single-page client application components.

What Is React?

React also known as ReactJS or React.js is a JavaScript library for building user interfaces. It was created by Facebook and is currently maintained by both Facebook and a community of individual developers. React was introduced in 2013 and is known for its simplicity and flexibility.

follows a component-based architecture, allowing developers to build reusable UI components. It is commonly used to create user interfaces for single-page applications from isolated components. It can handle web and mobile apps’ view layers. Thus, React supports web and mobile app development.

Angular vs React: A Detailed Comparison

1. Performance

2. Flexibility

3. Essential Tools

4. App Structure

5. Learning Curve

6. Dependency Injection (DI)

Example of Dependency Injection in Angular

import { Injectable } from '@angular/core';
import { HEROES } from './mock-heroes';
@Injectable({
  // we declare that this service should be created
  // by the root application injector.
  providedIn: 'root',
})
export class HeroService {
  getHeroes() { return HEROES; }
}

Example of Dependency Injection in React

import React from 'react';
import { ApiService } from './services/ApiService';

// Child component that consumes the ApiService
function ChildComponent({ apiService }) {
  // Use the injected ApiService
  // ...
}

// Intermediate component that passes the ApiService through props
function IntermediateComponent({ apiService }) {
  return ;
}

// Parent component that creates the ApiService and passes it through props
function ParentComponent() {
  const apiService = new ApiService();

  return ;
}

export default ParentComponent;

Here, The ParentComponent creates an instance of the ApiService and passes it through props to the IntermediateComponent. Then, the IntermediateComponent passes it further down to the ChildComponent.

7. Data Binding

Implementing Data Binding in Angular

1. Interpolation or String Interpolation

   
   // Component Class
   export class AppComponent {
       title = 'ScholarHat';
   }
   

   
   <!-- HTML Template --><h1>{{ title }}</h1>

2. Property Binding

   
   // Component Class
   export class AppComponent {
       imageUrl = 'path/to/image.jpg';
   }
   

   
   <!-- HTML Template --><img [src]="imageUrl" />

3. Event Binding

   
   // Component Class
   export class AppComponent {
       onClick() {
           console.log('Button clicked!');
       }
   }
   

   
   <!-- HTML Template --><button (click)="onClick()">Click me</button>

Implementing Data Binding in React

1. State
   • Class Components

     
     import React, { Component } from 'react';
     
     class MyComponent extends Component {
       constructor(props) {
         super(props);
         this.state = {
           message: 'ScholarHat'
         };
       }
     
       render() {
         return <div>{this.state.message}</div>;
       }
     }
     
     export default MyComponent;
     

   • Functional Components with Hooks (useState)

     
     import React, { useState } from 'react';
     
     function MyComponent() {
       const [message, setMessage] = useState('ScholarHat');
     
       return <div>{message}</div>;
     }
     
     export default MyComponent;
     

2. Props
   • Parent Component

     
     import React from 'react';
     import ChildComponent from './ChildComponent';
     
     function ParentComponent() {
       return <ChildComponent message="ScholarHat" />;
     }
     
     export default ParentComponent;
     

   • Child Component

     
     import React from 'react';
     
     function ChildComponent(props) {
       return <div>{props.message}</div>;
     }
     
     export default ChildComponent;
         

3. Event Handling

   
   import React, { useState } from 'react';
   
   function MyComponent() {
     const [count, setCount] = useState(0);
   
     const handleIncrement = () => {
       setCount(count + 1);
     };
   
     return (
       <div>
         <p>Count: {count}</p>
         <button onClick={handleIncrement}>Increment</button>
       </div>
     );
   }
   
   export default MyComponent;
       

8. State Management

State management is crucial for building scalable applications.

Example of State Management in Angular

export class HeroListComponent implements OnInit {
  heroes: Hero[];
  selectedHero: Hero;
  constructor(private service: HeroService) { }
  ngOnInit() {
    this.heroes = this.service.getHeroes();
  }
  selectHero(hero: Hero) { this.selectedHero = hero; }
}
    

Example of State Management in React

class Clock extends React.Component {
  constructor(props) {
    super(props);
  this.state = {date: new Date()};
 }
 render() {
   return (
    <div>
     <h1>Hello world!</h1>
     <h2>Now is {this.state.date.toLocaleTimeString()}.</h2>
    </div>
  );
 }
}
