Programming Crystal
Crystal is for Ruby programmers who want more performance or for developers who enjoy working in a high-level scripting environment. Crystal combines native execution speed and concurrency with Ruby-like syntax, so you will feel right at home. This book, the first available on Crystal, shows you how to write applications that have the beauty and elegance of a modern language, combined with the power of types and modern concurrency tooling. Now you can write beautiful code that runs faster, scales better, and is a breeze to deploy. Crystal is elegant to read and easy to program like Ruby, allowing full object-oriented development. Its compiler is powerful enough to nearly always infer the type of your variables. So you get the benefits of a statically typed language: more robust code, safety, and execution speed while still reaching high productivity in development. Null pointer exceptions as in JavaScript, Java, or C#, are a thing of the past: Crystal annihilates them, just like Rus ...

Build Reactive Websites with RxJS
Upgrade your skill set, succeed at work, and above all, avoid the many headaches that come with modern front-end development. Simplify your codebase with hands-on examples pulled from real-life applications. Master the mysteries of asynchronous state management, detangle puzzling race conditions, and send spaceships soaring through the cosmos. When you finish this book, you'll be able to tame the wild codebeasts before they ever get a chance to wreck your day. The front-end world can be fraught with complexity. The RxJS library offers a solution: Observables. Observables merge other JavaScript asynch mechanisms such as callbacks and promises into a new way of looking at data. Instead of dealing with objects and keeping track of their state, Observables view asynchronous events as a stream. RxJS provides you the tools to manage, manipulate, and process Observables to simplify and speed up your front-end applications. Never fear, you're in exactly the right place. Don't worry about ...
