Techniques for offloading computation
- [Instructor] Knowing how to offload computationally intensive tasks will enhance your application's performance and improve the overall user experience by distributing tasks across separate threads. What are web workers? JavaScript is single-threaded, only one task at a time. The problem is that heavy computations can block the main thread, making the UI sluggish. Web workers enable background threads, offloading tasks and keeping the UI responsive. In this file, we define a heavy computation function that simulates an intensive task. The worker listens for messages from the main thread, processes the data, and posts the result back. Now let's integrate this worker into our React component. In app.js, we create a new worker instance and send it a message to perform a heavy computation. The result is then set to the component state and displayed. This approach keeps the main thread free, ensuring the UI remains responsive. Now let's explore more advanced techniques for offloading…
