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.

With Visual Studio, we can also debug the JavaScript code by setting Internet Explorer as the default browser. Chrome is not supported out of the box, but with certain steps, its can be achieved.

Visual Studio provides certain decent features to debug JavaScript and troubleshoot errors. JavaScript debugging in Visual Studio only works with Internet Explorer. Debugging can be started by starting the application in a debug mode and then placing some breakpoints in the JavaScript code. When the breakpoint is hit, we can use all sorts of debugging options in Visual Studio that we already know of and used in debugging the C# and VB.NET code. Options such as Step into (F11), Step over (F10), Step out (Shift + F11), conditional breakpoints, and...
