Overview of this book

If you want to improve responsiveness or the UX in your ASP.NET applications, JavaScript can be a life saver. In an age where server-side operations have shifted to the client, being able to handle JavaScript with confidence and fluency is vital for ASP.NET developers. There’s no point trying to fight it, so start learning with this book. Make sure your projects exceed user expectations. Begin by getting stuck into the basics of JavaScript, and explore the language in the context of ASP.NET Core. You’ll then find out how to put the principles into practice, as you learn how to develop a basic ASP.NET application using Angular 2 and TypeScript. You’ll also develop essential skills required to develop responsive apps, with a little help from AJAX, ensuring that you’re building projects that can be easily accessed across different devices. With guidance on Node.js and some neat techniques to test and debug a range of JavaScript libraries in Visual Studio, you’ll soon be well on your way to combining JavaScript with ASP.NET in a way that’s capable of meeting the challenges of modern web development head-on.

TypeScript is a language developed by Microsoft and is a superset of JavaScript. TypeScript transpiles into JavaScript at compile time. Visual Studio 2015 automatically builds the TypeScript into JavaScript files and places them inside a folder configured with the TypeScript.tsconfig configuration file. It provides a lot more than JavaScript provides, but developers can still use some of the types and objects in TypeScript that they use in JavaScript. However, TypeScript generates cleaner and more optimized code, which is then run by the Angular 2 framework. So, when the TypeScript compiles, it generates JavaScript and stores a map file to handle debugging scenarios. Suppose you want to debug your TypeScript code from Visual Studio 2015; this mapping file contains the mapping information of the source TypeScript file and generated JavaScript file being run inside your Angular page and the break points can be set on your TypeScript file.
