    • Single-Page Application (SPA): Netflix uses JavaScript to create a seamless experience where users can navigate without reloading the page.
    • Node.js Backend: Netflix migrated its backend to Node.js for performance improvements and faster startup times, enhancing scalability and speed.

4. PayPal

  • Purpose: An online payments platform enabling secure money transfers.
  • Notable Techniques:
    • Node.js: PayPal adopted Node.js for its backend, reducing server response time and improving user experience.
    • JavaScript Full-Stack Development: With JavaScript on both the front and backend, PayPal has optimized its performance, increasing speed and flexibility.

5. LinkedIn

  • Purpose: A professional networking site connecting users for job searching, networking, and content sharing.
  • Notable Techniques:
    • Isomorphic JavaScript: LinkedIn uses isomorphic JavaScript to render components on both the client and server side, allowing faster page loads and better SEO.
    • Ember.js: Used to build dynamic interfaces and streamline development.

6. Uber

  • Purpose: A ride-hailing and transportation service connecting riders with drivers.
  • Notable Techniques:
    • Node.js Microservices: Uber leverages Node.js for managing real-time updates and handling thousands of user requests per second.
    • Mapbox GL JS: Uber uses JavaScript to power real-time map updates and route calculations on both mobile and web applications.

7. Slack

  • Purpose: A team communication and collaboration tool with chat, file sharing, and integrations.
  • Notable Techniques:
    • Electron Framework: Slack uses Electron to build its cross-platform desktop apps using JavaScript.
    • Real-Time Messaging: WebSockets are used to enable real-time messaging and notifications for users across devices.

8. Trello

  • Purpose: A project management tool for organizing tasks and collaborating in teams.
  • Notable Techniques:
    • React and Drag-and-Drop: Trello’s interactive UI is built with JavaScript using drag-and-drop features for easy task organization.
    • API Integrations: Trello integrates with other productivity tools through its JavaScript-powered API, enhancing its utility in workflows.

9. GitHub

  • Purpose: A platform for hosting, sharing, and collaborating on code repositories.
  • Notable Techniques:
    • React and Preact: GitHub uses JavaScript frameworks to create a fast and responsive interface, especially for code browsing and discussions.
    • Electron: GitHub Desktop, a cross-platform client, is built with Electron, enabling developers to interact with repositories on their desktops.

10. Discord

  • Purpose: A communication app popular among gamers and online communities for text, voice, and video chat.
  • Notable Techniques:
    • WebRTC and JavaScript: Enables high-quality voice and video communication directly within the app.
    • React and Electron: Used to create a unified experience on both desktop and web, enhancing real-time interactions.
