What is Concurrency?
Promises and Async/Await
Async/Await is a powerful syntactical feature introduced in ECMAScript 2017. We will delve into how Async/Await simplifies asynchronous code and makes it look more synchronous.
Introduction to Web Workers
Web Workers are a powerful mechanism for running scripts in the background, separate from the main UI thread. We will discuss how Web Workers can be used to achieve true parallelism and improve application performance.
Shared Workers allow communication between multiple instances of a web application. We will explore how Shared Workers facilitate intercommunication and data sharing between tabs or windows of the same application.
Leveraging Service Workers
Service Workers enable powerful features like offline support and push notifications. We will explore how Service Workers work, and how they can enhance the overall user experience by caching resources and providing real-time updates.
Background Sync is a feature offered by Service Workers that allows data synchronization even when the user is offline. We will discuss how Background Sync can be implemented to ensure data integrity.
Parallel Array Processing
Parallelism with Web Workers
Web Workers can be used for parallel array processing to optimize tasks that involve heavy computation. We will demonstrate how to leverage Web Workers to process arrays in parallel, reducing overall execution time.
Concurrency Patterns and Best Practices
Throttling and Debouncing
Throttling and debouncing are essential techniques for controlling the frequency of function execution. We will explore how to implement these patterns to optimize performance and prevent excessive function calls.
Concurrent Data Fetching
Managing multiple data fetch requests can be challenging. We will discuss strategies to handle concurrent data fetching, avoiding over-fetching and under-fetching data.
Real-time Data with WebSocket
Introduction to WebSockets
WebSockets offer bidirectional communication between the client and the server, facilitating real-time data updates. We will explore how WebSockets can be used to create real-time applications.
Implementing a Real-time Chat Application
As a practical example, we will build a real-time chat application using WebSockets, demonstrating the power of real-time data transmission.
