Concurrent programming may sound abstract and complex, but it helps to deliver a better user experience. With single threaded Java Script, applications lack dynamism. This means that when Java Script code is running, nothing else can happen. The DOM can’t update, which means the UI freezes. In a world where users expect speed and responsiveness – in all senses of the word – this is something no developer can afford.
Fortunately, Java Script has evolved to adopt concurrent capabilities – one of the reasons why it is still at the forefront of modern web development. This book helps you dive into concurrent Java Script, and demonstrates how to apply its core principles and key techniques and tools to a range of complex development challenges. Built around the three core principles of concurrency – parallelism, synchronization, and conservation – you’ll learn everything you need to unlock a more efficient and dynamic Java Script, to lay the foundations of even better user experiences.
Throughout the book you’ll learn how to put these principles into action by using a range of development approaches. Covering everything from Java Script promises, web workers, generators and functional programming techniques, everything you learn will have a real impact on the performance of your applications. You’ll also learn how to move between client and server, for a more frictionless and fully realized approach to development. With further guidance on concurrent programming with Node.js, Java Script Concurrency is committed to making you a better web developer.
The best developers know that great design is about more than the UI – with concurrency, you can be confident every your project will be expertly designed to guarantee its dynamism and power.
