React vs Vue: Understanding the Key Differences

Thabo | January 27, 2023

React and Vue are two of the most popular JavaScript libraries for building web applications. Both libraries have their own strengths and weaknesses, making it difficult to choose which one to use. In this post, we’ll take a look at the simple differences between React and Vue and why you might choose one over the other.

React is a JavaScript library developed and maintained by Facebook. It is used to build user interfaces and has a large community and ecosystem. React’s main feature is its use of a virtual DOM, which improves performance by reducing the number of updates to the real DOM. React also uses a component-based architecture, which makes it easy to reuse and compose components.

Vue, on the other hand, is a JavaScript framework developed and maintained by a group of individual developers. It is also used to build user interfaces, and it has a smaller community compared to React. Vue’s main feature is its easy learning curve, which makes it a good choice for developers new to JavaScript. Vue also uses a component-based architecture, similar to React.

When it comes to ease of use, Vue is often considered to be the simpler of the two. Vue’s template syntax is more straightforward, and it’s often easier to get started with. Vue also has a built-in set of directives that make it easy to handle common tasks like event handling and data binding.

React, on the other hand, can be more complex to get started with. React’s JSX syntax can take some getting used to, and it requires the use of additional libraries like Redux to handle state management. However, React’s virtual DOM and strong community make it a solid choice for building high-performance web applications.

Here is an example of a simple todo list app in React and Vue:

React Todo List App:

JSX

import React, { useState } from 'react';

function TodoList() {
  const [todos, setTodos] = useState([]);
  const [newTodo, setNewTodo] = useState('');

  const handleSubmit = (e) => {
    e.preventDefault();
    setTodos([…todos, newTodo]);
    setNewTodo('');
  }

  return (
    <div>
      <form onSubmit={handleSubmit}>
        <input type="text" value={newTodo} onChange={e => setNewTodo(e.target.value)} />
        <button type="submit">Add Todo</button>
      </form>
      <ul>
        {todos.map((todo, index) => (
          <li key={index}>{todo}</li>
        ))}
      </ul>
    </div>
  )
}

export default TodoList;

Vue Todo List App:

HTML

<template>
  <div>
    <form @submit.prevent="addTodo">
      <input v-model="newTodo" type="text" />
      <button type="submit">Add Todo</button>
    </form>
    <ul>
      <li v-for="(todo, index) in todos" :key="index">{{todo}}</li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      todos: [],
      newTodo: ''
    }
  },
  methods: {
    addTodo() {
      this.todos.push(this.newTodo);
      this.newTodo = '';
    }
  }
}
</script>

Both React and Vue are great choices for building user interfaces and it ultimately comes down to personal preference and the specific requirements of your project. For free hosting you can use Firebase hosting for both React and Vue app.
