Angular vs React: What is Different?

Let’s take a look at fundamental differences and compare technical functionalities between React and Angular.

Detailed Comparison React vs Angular

The main difference between React and Angular comes from various factors. We'll go through each of these differences step by step.

Language and Architechture

Let’s understand language and architecture first,

React: React utilizes JavaScript, providing flexibility and benefiting from a vast developer community. It manages applications by component-based method, simplifying the independent maintenance of UI elements.

Angular: Angular uses TypeScript, providing strong typing and excellent tooling. Its architecture follows a structured framework with predefined solutions. It encourages a modular approach, ensuring consistency and scalability in bigger projects.

Popularity

Statistics serve as a compass in tech, Let's look at some engaging numbers that will show you which framework is better performing in the industry.

React: React leads in popularity on Google Trends, indicating higher search interest. In a 2023 Statista survey, React ranked as the second most used global web framework, highlighting its widespread adoption.

According to BuiltWith statistics, approximately 13,717,538 clients use React. Moreover, React boasts 217k stars on GitHub, reinforcing its strong position in the development industry.

Angular: Angular appeals to developers with its comprehensive pre-built solutions, simplifying development. 

Around 365,390 websites use it, and it holds 93k stars on GitHub. Angular and React develop to meet industry needs, staying at the forefront of front-end development frameworks.

Data Binding

The main difference between Angular and React is how they handle state management. Let’s understand more.

React: React uses one-way data binding, rendering modifications in the UI model only after updating the model state first. And whenever the UI component gets changed, the state model remains the same. Check out the below example,

Example:

  
// Counter.js
import React, { useState } from 'react';

function Counter() {
const [counter, setCounter] = useState(0);

const increment = () => {
    setCounter(counter + 1);
};

return (
   <div>
          <h2>React Counter</h2>
          <p>Value: {counter}</p>
          <button onClick={increment}">Increment</button>
     </div>
);
}

export default Counter;                    

Angular: Angular supports both one-way and two-way data binding. In two-way, whenever any UI element changes, the model state also changes automatically. You can check below,

Example:

            
// app.component.ts

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

@Component({
    selector: 'app-root',
    template: `
         <div>
         <h2>Angular Counter</h2>
         <p>Value: {{ counter }}</p>
         <button (click)="increment()">Increment</button>
         </div>
    `,
    styleUrls: ['./app.component.css']
    })
export class AppComponent {
counter = 0;

increment() {
    this.counter++;
}
}
        

Componentization

Componentization in web development aims to split front-end features into separate components. These parts are self-contained, making them simpler to reuse, test, secure, deploy, and update without causing issues in the app. It helps to split the project among multiple developers and makes the app easier to scale with changing demands.

React: In React, developers combine components in JavaScript and HTML files written in JSX. They can be either class-based or pure functions, chosen based on what the developer needs. When passing information between components (using properties), React follows a one-way flow.

Example:

 
// Button.js
import React from 'react';
const Button = ({ label, onClick }) => (
    <button onClick={onClick}>{label}</button>
);
export default Button;


// App.js
import React from 'react';
import Button from './Button';

class App extends React.Component {
    onButtonClick = () => {
        console.log('Button clicked!');
    };
    
render() {
    return <Button label="Click me" onClick={this.onButtonClick} />;
}
}

export default App;
        

Angular: In Angular, components are marked with decorators like @Component, serving as functions that modify services, directives, or filters before using them. These decorators help identify if a class is a module or component and gather essential information to decide how a view should be displayed. 

Example:

            
// button.component.ts            
import { Component, Input, Output, EventEmitter } from '@angular/core';

@Component({
    selector: 'app-button',
    template: '<button (click)="onClick()">{{ label }}</button>',
    styles: ['button { cursor: pointer; }']
})

export class ButtonComponent {
    @Input() label: string = 'Click me';
    @Output() clicked: EventEmitter<void> = new EventEmitter<void>();
    onClick(): void {
    this.clicked.emit();
}
}

// app.component.ts
import { Component } from '@angular/core';
@Component({
    selector: 'app-root',
    template: '<app-button (clicked)="onButtonClick()"></app-button>'
})

export class AppComponent {
    onButtonClick(): void {
    console.log('Button clicked!');
}
}

DOM

The DOM (Document Object Model) is a graph that represents the user's current browser view. Developers modify the DOM to change the user's view, but these changes are costly based on performance. Both frameworks rely on the DOM differently. Let's check out how.

React: React uses a virtual DOM (Document Object Model), a lightweight copy of the actual DOM. It's an intermediary that sits between the developer's code and the real DOM. In React, when changes happen, it updates the virtual DOM. Then compares it with the previous version, identifies necessary changes, and updates only those specific parts in the real DOM. This approach reduces webpage manipulations, resulting in faster and more efficient updates.

Angular: Angular directly interacts with the real DOM. When changes occur, Angular directly modifies the real DOM, showing updates instantly. However, this method might involve more direct webpage manipulations compared to React's virtual DOM strategy, affecting performance, especially in complex applications.

Performance 

Angular and React are the leading forces in web app development, and each brings unique strengths for high performance. While React is renowned for its performance, Angular isn't far behind. Let's compare their performance!

React: React's virtual DOM is a key feature that boosts application performance. This feature lets developers make changes without rewriting the entire HTML document. Additionally, React renders updates and revives data on web pages for a smoother user experience.

The reusability factor in React components serves as a remarkable advantage, mainly when dealing with complex logic across different projects.

Designers also benefit from React's component reusability, which doubles productivity and simplifies coding practices. From simple checkboxes and buttons to wrapper and root components, this method ensures consistent app performance. These practices also enhance code quality and maintenance, providing high performance across applications.

Angular: Angular allows you to fine-tune code structures, mainly by optimizing the digest cycle. This approach ensures better performance as codebases expand to include multiple modules. Monitoring and optimizing the loop contribute to verifying and incorporating previously assessed improvements.

For projects that do not need two-way data binding, older Angular versions simplify processes. Angular's $cacheFactory feature aids in data memorization and recalculations, enhancing overall performance.

Angular uses the real DOM for rendering but employs a unique change detection mechanism with zones. This combination ensures swift application updates, contributing to faster and optimized web experiences.

Learning Curve

React: React's learning curve is more user-friendly. It relies on JavaScript and JSX, enabling quick application development. Its focus is on a component-based approach. And simpler concepts make it an accessible choice for beginners in front-end development.

Angular: Learning Angular requires handling its powerful but complex framework. It involves understanding TypeScript, modules, and complex dependency injection, demanding dedicated effort for proficiency due to its structured nature.

Community and Ecosystem

React: React has a large and active community supported by numerous libraries and tools. Its ecosystem comprises a multitude of third-party integrations, offering solutions for various needs. This vibrant community continually contributes to React's growth and evolution.

Angular: Angular boasts a robust community with extensive documentation and support. Its ecosystem includes a comprehensive set of tools, libraries, and official resources backed by Google. This well-organized community fosters continuous enhancements and provides complete solutions for developers.

Code Quality and Maintenance

Angular: Angular's structured approach, enforced by its opinionated nature, offers a clear path for developers. Its built-in tools and adherence to TypeScript ensure robust code and early error detection, making maintenance smoother in the long run. However, its strict conventions and steep learning curve can be hurdles for newcomers, requiring dedication to master and maintain code consistency.

React: React's flexibility empowers developers to build applications in a way that suits their needs. Its component-based architecture promotes code reusability and separation of concerns, simplifying maintenance tasks. Yet, this freedom comes with the responsibility of making decisions about project structure and tooling, which may result in inconsistencies across projects if not managed carefully.
