Join the AI Workshop to learn more about AI and how it can be applied to web development. Next cohort February 1st, 2026
The AI-first Web Development BOOTCAMP cohort starts February 24th, 2026. 10 weeks of intensive training and hands-on projects.
JavaScript has a rich ecosystem of libraries and tools that extend the language’s capabilities. While modern JavaScript and browser APIs have reduced the need for some of these libraries, they remain important to understand—both for maintaining existing codebases and for solving specific problems more efficiently.
In this unit, we’ll explore several popular JavaScript libraries:
- jQuery - The library that revolutionized DOM manipulation (now mostly historical)
- Axios - A popular HTTP client for making API requests
- Moment.js - Date manipulation made easy (with notes on modern alternatives)
- SWR - React Hooks for data fetching
- XState - State machines for predictable state management
- PeerJS - Simplified WebRTC for peer-to-peer communication
