Svelte vs React vs Vue comparison

Introduction

These three are popular tools to build websites and apps. Knowing their differences helps you pick the best one for your project.

You want a fast website with less code to write.

You want a big community and lots of ready-made parts.

You want simple setup and easy learning.

You want to build interactive user interfaces.

You want good support for mobile-friendly design.

Syntax

Svelte

Svelte: Uses components with HTML, CSS, and JS in one file.
React: Uses JavaScript with JSX to describe UI.
Vue: Uses single-file components with template, script, and style sections.

Svelte compiles your code to efficient JavaScript before running.

React and Vue run mostly in the browser to update the UI.

Examples

Svelte example: simple and clean with reactive variables.

Svelte

<script>
  let count = 0;
</script>
<button on:click={() => count++}>
  Clicked {count} times
</button>

React example: uses useState hook and JSX syntax.

Svelte

import React, { useState } from 'react';

function Counter() {
  const [count, setCount] = useState(0);
  return (
    <button onClick={() => setCount(count + 1)}>
      Clicked {count} times
    </button>
  );
}

Vue example: template with reactive ref variable.

Svelte

<template>
  <button @click="count++">
    Clicked {{ count }} times
  </button>
</template>

<script setup>
import { ref } from 'vue';
const count = ref(0);
</script>

Sample Program

This Svelte component lets you pick a framework from a dropdown and shows a short description. It updates instantly when you change the selection.

Svelte

<script>
  let framework = 'Svelte';
  let description = {
    Svelte: 'Compiles to fast JavaScript with less code.',
    React: 'Uses JSX and a large ecosystem.',
    Vue: 'Easy to learn with flexible templates.'
  };
</script>

<h1>{framework} vs React vs Vue</h1>
<p>{description[framework]}</p>

<select bind:value={framework} aria-label="Choose framework">
  <option value="Svelte">Svelte</option>
  <option value="React">React</option>
  <option value="Vue">Vue</option>
</select>

Important Notes

Svelte updates the page by compiling away the framework code, making apps fast.

React has a huge community and many tools but needs more setup.

Vue is beginner-friendly and balances features and simplicity well.

Summary

Svelte is great for speed and simplicity.

React is powerful with a big ecosystem.

Vue is easy to learn and flexible.
