Introduction to Web Workers
In modern web development, JavaScript is the backbone of building dynamic and interactive web applications. However, as applications grow more complex, handling tasks that require significant processing power can become challenging. JavaScript is single-threaded, meaning it can only perform one operation at a time, which can lead to performance issues when executing heavy tasks like data processing or image manipulation.
This is where Web Workers come in. Web Workers allow you to run scripts in background threads, separate from the main execution thread of your web application. By offloading complex tasks to Web Workers, you can keep your application responsive and avoid blocking the user interface.
In this lesson, we’ll dive deep into the Web Workers API, exploring how to create and manage Workers, handle communication between threads, and apply these techniques to real-world scenarios. Whether you’re building a high-performance web application or just curious about concurrency in JavaScript, this lesson will provide you with the knowledge and tools to effectively utilize Web Workers in your projects.
