1. Using Console
Visual Studio has a built-in console that permits you to log error messages, warnings, and additional data about the code. By adding the statement console.log() to your code, you can access it. Look at this code snippet that logs “Hello World” to the console.
You can also debug your web applications by setting breakpoints in your code. Enjoy the strength of viewing the debug console to see the objects, variables, and data hooked up with that specific part of the code when the code hits the breakpoint.
2. Debugging with Breakpoints
Are you in the mood for an incredibly powerful feature? Look no further than the breakpoints. It allows you to stop the execution of your code at specific lines or statements. You can analyze the values of objects and variables at that point in the code, execute the code line-by-line, and identify bugs more quickly and efficiently.
Visual Studio permits you to set a breakpoint by clicking on the margin to your desired line. A red dot will appear, indicating the exact line the breakpoint has been set. Once the code execution reaches that specific line, it will stop, and you’ll undoubtedly enjoy the various debugging features to examine and modify the code.
Moreover, you can set conditions on breakpoints, which will only trigger if the condition evaluates to true. This allows you to stop execution when a particular variable reaches a specific value or satisfies particular conditions.
3. Using the Debugger in Visual Studio
To use the debugger, you first need to kick start your code in debug mode. By pressing the F5 key or selecting “Start Debugging” from the Debug menu, you can instantly set your code in debug mode. Once your code is in debug mode, you can set breakpoints and use various debugging tools to identify and fix bugs.
The debugger provides you with the ability to step through your code line-by-line, execute code and examine the values of variables and objects in real-time. You can also evaluate expressions and run code snippets in the context of your code. Let the magic unfold!
4. Debugging with Third-Party Tools and Plugins
Chrome DevTools is a Herculean set of debugging tools that allow you to inspect and modify live web content. It includes a debugger, a profiler, and a console interface that allows you to log data and execute code in the context of the page. Firebug is another famous tool that provides similar features and is available as a plugin for Firefox.
Edge Developer Tools is a set of debugging tools built into the Microsoft Edge browser. It includes a debugger, a console, and a profiler that allows you to examine and modify the code in real-time. Buckle up for a smooth ride!
