Overview of this book

The ASP.NET Core 2.0 Framework has been designed to meet all the needs of today’s web developers. It provides better control, support for test-driven development, and cleaner code. Moreover, it’s lightweight and allows you to run apps on Windows, OSX and Linux, making it the most popular web framework with modern day developers. This book takes a unique approach to web development, using real-world examples to guide you through problems with ASP.NET Core 2.0 web applications. It covers Visual Studio 2017- and ASP.NET Core 2.0-specifc changes and provides general MVC development recipes. It explores setting up .NET Core, Visual Studio 2017, Node.js modules, and NuGet. Next, it shows you how to work with Inversion of Control data pattern and caching. We explore everyday ASP.NET Core MVC 2.0 patterns and go beyond it into troubleshooting. Finally, we lead you through migrating, hosting, and deploying your code. By the end of the book, you’ll not only have explored every aspect of ASP.NET Core MVC 2.0, you’ll also have a reference you can keep coming back to whenever you need to get the job done.

Debugging JavaScript code in browsers


JavaScript code is executed in the browser. We (as developers) use intelligent IDEs, intelligent test frameworks, and so on to build an application easily. But sometimes, when the browser executes our intelligently-built code, something we didn't expect happens, and our code breaks.

Bugs can be syntax errors. These kinds of bugs are easy to determine. Most IDEs have some built-in tools to determine syntax errors, and even provide smart fixes.

Some bugs are logical errors. These kinds of bugs aren't easy to determine, yet most IDEs have no support to determine logical errors.

So, we need tools to debug our code in the execution environment, namely, the browser.

Getting ready

All browsers have an inner mechanism that understands and executes JavaScript code. This mechanism is called the JavaScript Engine.

The main job of a JavaScript Engine...
