About This Book
- Apply the core principles of concurrency to both browser and server side development
- Explore the latest tools and techniques at the forefront of concurrent programming, including JavaScript promises, web workers, and generators
- Learn how concurrent and parallel programming can help you tackle the challenges of fast, data heavy web development
Who This Book Is For
This book is written for any JavaScript developer who wants to learn how to write more efficient, powerful, and maintainable applications that utilize the latest developments in JavaScript.
What You Will Learn
- Understand exactly how JavaScript works in a web browser environment and how these mechanisms power our event-driven JavaScript code
- Use promises to turn complex synchronization scenarios into readable and maintainable code
- Compute values lazily and avoid unnecessary memory allocations using generators
- Write concurrent code that doesn't feel like concurrent code by abstracting away boilerplate chores
- Leverage true hardware parallelism with web workers to get better performance
- Get to grips with the NodeJS model of concurrency and learn why it's good for I/O-intensive web applications
In Detail
JavaScript 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 JavaScript and demonstrates how to apply its core principles, key techniques, and tools to a range of complex development challenges. Built around the three core principles of concurrency―parallelism, synchronization, and conservation―you will learn everything you need to unlock a more efficient and dynamic JavaScript in order to lay the foundations of even better user experiences.
Throughout the book you will learn how to put these principles into action by using a range of development approaches. Covering everything from JavaScript promises, web workers, and generators to functional programming techniques, everything you learn will have a real impact on the performance of your applications. You will also learn how to move between the client and server for a frictionless and fully realized approach to development. With further guidance on concurrent programming with NodeJS, JavaScript Concurrency is committed to making you a better web developer.
Build better software with concurrent JavaScript programming, and unlock a more efficient and forward thinking approach to web development About This Book * Apply the core principles of concurrency to both browser and server side development * Explore the latest tools and techniques at the forefront of concurrent programming, including JavaScript promises, web workers, and generators * Learn how concurrent and parallel programming can help you tackle the challenges of fast, data heavy web development Who This Book Is For JavaScript Concurrency is written for any JavaScript developer who wants to learn how to write more efficient, powerful, and maintainable applications that utilize the latest developments in the JavaScript language. All aspects of concurrent, asynchronous, and parallel programming are covered from first principles and by the end of the book you'll be able to create a fully-worked application that leverages all the topics covered in the book.

With single threaded JavaScript, applications lack dynamism. This means that when JavaScript 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
