Description
The Joy of JavaScript introduces techniques that turn JavaScript programmers into JavaScript pros.
Summary
Whether building interactive browser-based applications or creating server-side applications in Node, JavaScript is the most widely used language for web programming. With new features, language improvements, paradigms, and potential use cases appearing regularly, there's never been a more exciting time to be a JavaScript developer. In The Joy of JavaScript, author and JavaScript expert Luis Atencio teaches you key design concepts that lead to clean, lean, modular, and easy-to-maintain code.
Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.
About the technology
JavaScript is at the heart of web applications on the browser side and, via the popular Node.js runtime, it often powers the server side too. Simply put, the web runs on JavaScript.
About the book
The Joy of JavaScript introduces techniques that turn JavaScript programmers into JavaScript pros. You'll work with cutting edge APIs, language features, and coding styles to tackle tricky problems in an elegant manner. Along the way, you'll practice good object design, drive business logic with functional thinking, and untangle complex data flows.
What's inside
JavaScript's objects and module system
Working with higher order functions
Identifying and creating composable software
Preparing for upcoming JavaScript features
About the reader
Written for experienced and passionate JavaScript developers.
About the author
Luis Atencio is a software engineer for Citrix Systems, author of Manning's Functional Programming in JavaScript, and co-author of Manning's RxJS in Action.
