One of the major reasons why you should learn JavaScript in 2021 is its omnipresence. You can find JavaScript everywhere. Conversly, this means that learning JavaScript is a valuable skill regardless of what you want to develop.

With JavaScript, you can…

🌐 …create websites / web apps and browser extensions. Check!
🖥️ …create desktop apps. Check!
📱 …create mobile apps. Check!
🎮 …create games. Check!

This leaves nothing to be desired. In this post I'll show you awesome JavaScript frameworks, libraries and tools for the different use-cases. The only limit is your imagination. Also, you'll find examples of possible applications. So, if you wonder whether JavaScript is good enough - take a look at the examples.

🌐 Frontend Development

Frameworks / Libraries

• Angular
• Aurelia
• React
  • Gatsby
  • Next.js
• Svelte
• Vue.js
  • Gridsome
  • Nuxt.js

Examples

Virtually every website uses JavaScript. I think that should give enough examples of the possible applications. Also, these frontend frameworks and libraries are used for the interfaces in desktop / mobile apps and games as well.

🌐 Backend Development

Runtimes

• Node.js
• Deno

Frameworks / Libraries

• Express
• Fastify
• hapi
• Koa
• NestJS

Examples

• Netflix
• PayPal
• Trello

🖥️ Desktop Development

Frameworks / Libraries

• AppJS
• Electron
• NodeGui
• NW.js
• Proton Native

Examples

• Discord
• Postman
• Slack

📱 Mobile Development

Frameworks / Libraries

• Cordova
• Ionic
• NativeScript
• React Native
• Weex

Examples

• Instagram
• Pinterest
• Wix

🎮 Game Development

Frameworks / Libraries

• Bablyon.js
• Colyseus
• GDevelop
• Phaser
• PixiJS

Examples

• Aviary Attorney
• Curious Expedition 2
• slither.io

Conclusion

There you have it. If anyone ever tells you again, that JavaScript can't be used here or there - think twice. They might be right, but that's almost never true. Some applications require something else than JavaScript. Though, for your typical use-case (like Netflix or PayPal, lol), JavaScript is good enough.

However, let me add that even these big companies probably have a more diverse tech stack. JavaScript is a puzzle piece that let's you move fast and focus on the bigger picture. If you need something else, you probably know it and choose accordingly.
