JavaScript Frameworks Overview

The JavaScript ecosystem offers a vast array of frameworks and libraries for building modern web applications. From libraries like React to full-stack frameworks like Next.js and Astro, each tool has its own philosophy, strengths, and ideal use cases. This guide covers the most popular options to help you choose the right tool for your project.

Framework Deep Dives

For detailed information about specific frameworks, see:

React - Component-based UI library
Vue - Progressive framework
Svelte - Compiler-based framework
Angular - Full enterprise framework
Next.js - Full-stack React framework
Astro - Content-first framework

Understanding the Landscape

Libraries vs Frameworks

Library (e.g., React)

You call the library's code
More flexibility, less opinionated
You choose routing, state management, etc.

Framework (e.g., Angular, SvelteKit)

The framework calls your code
More opinionated, includes more features
Routing, state management often built-in

UI Frameworks vs Full-Stack Frameworks

UI Framework: Focuses on building user interfaces

React, Vue, Svelte, Solid

Full-Stack Framework: Includes server-side rendering, routing, data fetching

Next.js, Astro, SvelteKit, Remix, Nuxt

The Big Five

1. React

Type: Library (not a framework) First Released: 2013 Creator: Facebook (Meta) Philosophy: Component-based, declarative UI

→ Read the full React guide

Quick Overview:

function Counter() {
  const [count, setCount] = useState(0);

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={() => setCount(count + 1)}>
        Increment
      </button>
    </div>
  );
}

Strengths:

Largest ecosystem and community
Component reusability
React Native for mobile
Backed by Meta (Facebook)
Excellent TypeScript support

Considerations:

Not a full framework (need to add routing, etc.)
Requires more decision-making (choice paralysis)
Larger learning curve than some alternatives

Best For:

Large-scale applications
Teams with React experience
When you need maximum flexibility
Mobile apps (React Native)

Popular With:

Next.js (full-stack framework)
Remix (full-stack framework)
Gatsby (static sites)

2. Vue

Type: Progressive framework First Released: 2014 Creator: Evan You Philosophy: Approachable, versatile, performant

→ Read the full Vue guide

<template>
  <div>
    <p>Count: {{ count }}</p>
    <button @click="count++">Increment</button>
  </div>
</template>

<script setup>
import { ref } from 'vue';

const count = ref(0);
</script>

<style scoped>
button {
  background: blue;
  color: white;
}
</style>

Strengths:

Gentler learning curve than React
Single-file components (HTML, JS, CSS together)
Excellent documentation
Built-in state management (Pinia/Vuex)
Great for gradual adoption

Considerations:

Smaller ecosystem than React
Less used in large enterprises
Fewer job opportunities than React

Best For:

Solo developers or small teams
Gradual adoption into existing projects
Rapid prototyping
Developers who prefer template syntax

Popular With:

Nuxt (full-stack framework)
Vite (build tool, created by Vue author)

3. Svelte

Type: Compiler (compiles to vanilla JS) First Released: 2016 Creator: Rich Harris Philosophy: No virtual DOM, compile-time optimizations

→ Read the full Svelte guide

<script>
  let count = 0;

  function increment() {
    count += 1;
  }
</script>

<div>
  <p>Count: {count}</p>
  <button on:click={increment}>
    Increment
  </button>
</div>

<style>
  button {
    background: blue;
    color: white;
  }
</style>

Strengths:

Smallest bundle sizes (no runtime)
Fastest performance (compile-time optimizations)
Extremely clean, readable syntax
Built-in reactivity (no useState, etc.)
Built-in animations and transitions

Considerations:

Smaller ecosystem than React/Vue
Fewer third-party component libraries
Less TypeScript support (improving)

Best For:

Performance-critical applications
Small bundle sizes matter
Interactive visualizations
Developers who want simplicity

Popular With:

SvelteKit (full-stack framework)
Vite (build tool)

4. Solid

Type: Reactive framework First Released: 2018 Creator: Ryan Carniato Philosophy: Fine-grained reactivity, React-like syntax

import { createSignal } from 'solid-js';

function Counter() {
  const [count, setCount] = createSignal(0);

  return (
    <div>
      <p>Count: {count()}</p>
      <button onClick={() => setCount(count() + 1)}>
        Increment
      </button>
    </div>
  );
}

Strengths:

Fastest performance (even faster than Svelte)
No virtual DOM overhead
React-like syntax (easy for React devs)
True reactivity
Small bundle size

Considerations:

Much smaller ecosystem
Fewer learning resources
Less mature tooling
Smaller community

Best For:

Performance-obsessed developers
React developers wanting better performance
Applications with complex reactive state

Popular With:

SolidStart (full-stack framework)

5. Angular

@Component({
  selector: 'app-counter',
  template: `
    <div>
      <p>Count: {{ count }}</p>
      <button (click)="increment()">Increment</button>
    </div>
  `
})
export class CounterComponent {
  count = 0;

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

Strengths:

Complete solution (routing, forms, HTTP, etc.)
Excellent TypeScript support (built with TS)
Strong opinions reduce decision fatigue
Enterprise-friendly
