<ul><li>Web Workers are a feature of the Web API that allows JavaScript code to run in the background on a separate thread, improving performance by offloading resource-intensive tasks from the main thread.</li><li>Web Workers operate in a different execution context and can communicate with the main thread via messages. They do not have access to the DOM, window, or document objects.</li><li>To use Web Workers, create a separate JavaScript file containing the code to be executed in the background. Initialize the worker in the main thread, send and receive data through messages, and terminate the worker when no longer needed.</li><li>Web Workers offer improved performance, better user experience, and scalability by preventing the main thread from being blocked, allowing the UI to remain responsive even during intensive operations.</li></ul>
