Study Notes
JavaScript Use Cases
- JavaScript is used extensively in web browsers for interactive features (e.g., adding to cart).
- It powers websites on servers, interacts with databases, and provides app functionality.
- Used in mobile app development (React Native).
- Used to program Internet of Things (IoT) devices.
Browser Compatibility Issues
- Different browsers in the early 2000s had variable JavaScript behavior.
- This led to developers writing separate code for each browser.
- This was inefficient and caused user experience problems.
jQuery as a Solution
- jQuery was a JavaScript library that addressed the browser compatibility issue.
- It simplified cross-browser JavaScript development.
- Its broad usage made it a staple for over a decade.
Evolving JavaScript Technologies
- As web development evolved, new problems and technologies arose.
- React emerged in 2011, changing website development approaches, addressing issues related to complex websites.
- Other JavaScript frameworks also emerged (e.g., Knockout, Backbone, Angular, Ember, Vue, Alpine).
Legacy Code
- Millions of websites use JavaScript from various versions and libraries.
- This code is often considered legacy code.
- While not commonly used in modern development, developers might encounter it.
Mastering JavaScript Principles
- Don't feel the need to learn every JavaScript technology.
- A strong understanding of plain JavaScript is foundational to learning more complex frameworks like React.
