WebWorkers is a multi-threaded mechanism provided by HTML5, which is used to run scripts in the browser background without blocking the main thread. It allows for tasks such as complex calculations, data processing, etc. while keeping the page responsive. The steps to create and use WebWorker include: 1. Create an external JavaScript file (such as worker.js); 2. Detect browser support on the main page; 3. Instantiate Worker objects; 4. Use postMessage() to send messages; 5. Receive results through onmessage. Its limitations include inability to operate the DOM, limited communication methods, and inconvenient debugging. Applicable scenarios include mathematical calculations, timing tasks, data encryption, image processing, etc. Use We reasonably

WebWorkers prevents page freezing by running JavaScript in a separate thread. It is suitable for tasks such as data encryption, image processing, and complex computing. When using it, you need to create a separate file (such as worker.js) and communicate through postMessage() and onmessage. However, Worker cannot access DOM, window or document objects, nor can it directly update the UI. In addition, Worker needs to be loaded via HTTP(S) and should be reused as much as possible to reduce overhead, and pay attention to processing errors and message size optimization.

WebWorkers is a multi-threaded mechanism provided by the browser, which is used to place time-consuming tasks on the background thread to execute, avoiding blocking the main thread. 1. Worker does not have DOM operation permissions, and can only pass messages through postMessage and onmessage; 2. Creating a Worker requires a separate JS file and instantiated through newWorker(); 3. Common uses include data processing, image audio processing, JSON parsing, game AI computing, etc.; 4. Pay attention to cross-domain restrictions, resource consumption control and compatibility issues when using it. The rational use of WebWorkers can significantly improve web page performance and user experience.

WebWorker is a multithreaded mechanism of HTML5, used to perform time-consuming tasks in the background without blocking the main thread. 1. It allows JavaScript operations to be put into independent threads to run, such as data encryption, image processing, etc.; 2. Worker communicates with the main thread through postMessage(), and does not support DOM operations and alert(), etc.; 3. The creation method is newWorker('worker.js'), and listens to messages in the main script and Worker script respectively; 4. Pay attention to homologous policies, memory management and compatibility issues when using them.

To realize the parallax scrolling effect in HTML5, you need to combine HTML, CSS and JavaScript. The core is to allow different page elements to scroll at different speeds. 1. The HTML structure should contain multiple independent layers, such as using different class names to represent background, intermediate content and foreground. 2. CSS uses position:absolute and translateZ to create a 3D depth sense. The smaller the value of the background layer, the slower the scrolling. 3. JavaScript can listen to scroll events, dynamically adjust the translateY value, and control the scroll speed of each layer by multiplying by a coefficient. 4. Pay attention to performance optimization and use requestAnimationFrame
