Java and JavaScript handle tasks differently. Java uses many threads. JavaScript uses one thread.

Java builds large systems. It runs many tasks at once. This increases speed.

JavaScript runs in web browsers. Browsers change the page. Multiple threads would fight over the same page. This creates bugs. JavaScript runs one task at a time to stay safe.

JavaScript uses an event loop for multitasking. It does not stop while waiting for an API. It runs other code. It handles the API response later.

Web Workers allow background tasks. They handle heavy math. This keeps the main page fast. The core remains single-threaded.
