Web Programming: Front-end Frameworks (React, Angular, Vue.js)

What is a Front-end Framework?

A front-end framework is a set of tools and libraries that facilitate the construction of interactive user interfaces in web applications. They allow you to structure your code efficiently and reuse it.

Main Front-end Frameworks

• React: A library developed by Facebook, based on reusable components and the use of a Virtual DOM to improve performance.
• Angular: A complete framework developed by Google that follows the MVC pattern and provides advanced tools for developing enterprise applications.
• Vue.js: A progressive, easy-to-learn, and flexible framework, ideal for scalable and dynamic projects.

Example of a React Component

This code shows how to create a simple React component:

import React from "react";

function Greeting() {
    return <h1>Hello, World from React!</h1>;
}

export default Greeting;

React allows you to reuse components and manage state efficiently.

Example of an Angular Component

This code shows a basic Angular component:

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

@Component({
  selector: 'app-greeting',
  template: '<h1>Hello, World from Angular!</h1>',
  styles: ['h1 { color: blue; }']
})
export class GreetingComponent { }

Angular uses TypeScript and a module- and component-based architecture.

Example of a Vue.js Component

This code shows a simple Vue.js component:

<template>
  <h1>¡Hello World From Vue.js!</h1>
</template>

<script>
export default {
  name: "Hello"
};
</script>

<style>
h1 {
  color: green;
}
</style>

Vue.js is intuitive and easy to integrate into existing projects.

Conclusion

React, Angular, and Vue.js are powerful options for developing modern web interfaces. Choosing the right framework depends on the type of project and the developer's preference.
