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?

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?

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.

Angular vs React: A Thorough Comparison

1. Performance

Angular vs React performance

Performance in AngularPerformance in React
Angular is generally considered to be quite fast. This is partly because of the use of the AOT (Ahead-of-Time) compiler, which compiles your code before it’s sent to the browser, making it faster to load and execute.Even with Angular’s AoT compiler, React is faster than Angular
It uses traditional DOM that updates the whole webpage even with the change of a single element.It uses the concept of virtual DOM putting less load on the browser.
It has bidirectional data binding. Therefore, the more bindings you have, the more watchers are created, and the more cumbersome the process becomes.Since the data-binding process is unidirectional, bindings are not assigned watchers as in the case of Angular.

2. Flexibility

Angular vs React Flexibility

Flexibility in AngularFlexibility in React
Angular is an opinionated framework and provides a lot of built-in features out of the box.React is very flexible and allows developers to do whatever they want with the code.
Angular offers a wide range of options like templates, custom directives, and components for customizing the code and adapting it to a project’s needs.Here developers have a lot of freedom to create custom components and tailor their code to their project’s needs.
This can be limiting if we want to do something that’s either not supported or not clearly defined.It can be overwhelming because there are so many options and decisions to make.

3. Essential Tools

4. App Structure

Angular vs React App structure

App Structure in AngularApp Structure in React
The structure of Angular is fixed and complexThe structure of React provides developers with the freedom to choose. There is no “the only right structure” for a React app.
Angular is based on three layers – Model, Controller, and View.React offers only the View layer, while Model and Controller are added with the usage of other libraries.

5. Learning Curve

Angular vs React Learning Curve

Learning Curve for AngularLearning Curve for React
Angular is a complete MVC framework.React is a library and not a framework.
Knowledge of TypeScript, a superset of JavaScript is a must to learn Angular.It doesn’t require mastering JavaScript. It is simple to understand if you are familiar with the language
Angular is more complex to understand, there is a lot of unnecessary syntax, and component management is intricate.React is minimalistic: no dependency injection, no classic templates, no overly complicated features. Hence, easy for beginners.

6. Dependency Injection (DI)

Dependency Injection in AngularDependency Injection in React
Angular supports dependency injection accommodating flexibility in both testing and debugging.React does not fully support dependency injection as it does not fully comply with the idea of functional programming and data immutability.
It works through Dependency Injection Containers, Providers, Injection Tokens and InjectorsIt takes place through props and children.

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

Data Binding in AngularData Binding in React
Angular uses two-way data binding, also known as bidirectional data binding. Therefore if you change something in the UI, it also reflates at the other end in a component class. React uses unidirectional data binding. A unidirectional data binding indicates a one-way parent-to-child data flow. Therefore, you can’t trace it backward.
It’s a comparatively slower process It’s a comparatively faster process

Implementing Data Binding in Angular

 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

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.

State Management in AngularState Management in React
NGRX is a state management library, which permits the use of reactive state management.Generally, REDUX works as a state management library for React.
In Angular, component data is stored in component properties. Parent components pass data through to children.In React, every React component can have a state, so it’s necessary to manage the states of these components separately.

Example of State Management in Angular

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

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>
  );
 }
}    

9. UI Components

AngularReact
Angular has a built-in Material toolset, and it offers a variety of pre-built material design components.UI tools for React are developed by the community. There are a lot of free and paid UI components on the React portal.
UI configuration becomes simpler and faster due to this.To use material design components in React, you would have to install an additional library – Material-UI Library & Dependencies.
