    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.
