Debuggers in browsers allow developers to inspect and debug the code running in a web browser. At the same time, a standalone debugging tool is a separate software that has advanced features like integrations, multi-language support, and many more.
What is Debugging and its Advantages?
Debugging means the process of removing errors from computer hardware and software. In context to programming, it is the process of finding and fixing errors from the source code of the web pages or software.
When dealing with programming or web pages there are chances of errors. It could be some syntax errors or minor bugs that can be a troublemaker of your code structure. Therefore, practicing debugging with your code can save a lot of time by preventing such causes.
Now, debugging and testing are both different processes, testing reveals the effect of the mistakes in the code. In addition, it will not help the developer to point out the error in the code whereas, debugging will help you to identify and fix the code.
Advantages of Debugging
- Improved functionality
- Better user experience
- Code quality
- Effective troubleshooting
- Quality assurance
- Better collaboration, and many more…
Note: If you want to accelerate the debugging part, we recommend using a ready-to-use template in which you will get access to the source of the Admin dashboard templates that are error-free and production-ready.
Generally, web browsers come with built-in debuggers in the browser that we will discuss later on in this post. These debuggers helped the developers to analyze their web pages with advanced features and functionalities.
Now, that we have got the details about debugging and its advantages let’s directly head on to the list without wasting any time.
Debuggers used in Browsers
Chrome is considered to be the most used browser among users. The browser is built by Google which offers Chrome DevTools. Besides, it has a set of web developer tools that are built directly into the browser.
It can help you edit pages while browsing, managing workflows, debugging, and prototyping CSS. Furthermore, it lets you change the profiling page, load performance, and monitor network requests.
Safari Web Inspector
The web inspector mode in Safari provides the developer quick and easy access to development tools in a web browser. Furthermore, it lets them inspect and select individual HTML elements on a web page, view attributes, and styles and modify them in real-time.
The debugger supports source maps, allowing developers to debug code that can be minified and transpired into other languages like TypeScript. In addition, you can set breakpoints and step through your code during the debugging process.
To initiate debugging, you can select the debugger tab in the Developer tools window. The shortcuts are similar we used in other browsers.
For instance, users can create new bins (code snippets) by typing the code in the editor. Also, you can share these code snippets with others by providing a unique URL. You can use JS Bin to isolate and replicate bugs that demonstrate a particular problem. Then share the URL to the JS Bin either as the full output or the editor view of the JS Bin.
- Live reload both in the editor and in full preview
- Full unmodified rendered view
- Linting with full config control
- Library support
- Custom URLs, and many more…
To debug in VS code you need to select Run and Debug on the start view or use the shortcut key
F5. This will start debugging your currently active file.
Moreover, it allows you to configure and save debugging details because, while debugging creating a launch configuration file is important.
- Data Inspection
- Variable substitution
- Debug Console
- Multi-language support, and many more…
Webstorm is one of the best IDEs in programming used by developers. In addition, it is known for providing a development experience that is enjoyable for handling complex tasks easily.
Furthermore, it lets you put the breakpoints and step through in your actual source code.
- Evaluate expression
- Stepping through the code
- App State and call stack
- Debug tool window
- Remote debugging
- Debugging configuration and many more…

- Remote debugging
- Call Stack view
- Expression View
- Step into/over/out
- Console view, and many more…
In addition, it has a built-in debugging tool in which you can fix your codes using its helpful features.
For instance, it has a real-time connection to the browser in which you can make changes to HTML and CSS as per the changes you want on your screen. Furthermore, it lets you set breakpoints at specific lines in your code to pause the execution and examine your code.
- Step-by-step execution
- Inline editors
- Conditional breakpoints
- Node debugger
- Live preview, and many more…
Moreover, the purpose of an individual while debugging a code is to maintain the quality of the code. In addition, it provides its stakeholders with a quality-assured web app that is bug-free. Therefore, the above-mentioned debuggers will surely help you to achieve such needs.
Now, selecting among these debuggers will depend upon individual needs and requirements. For instance, if you want to do the usual debugging on the real-time page then you can go for browser-based web developer tools.
Apart from this, we suggest using UI kits while working on any web app as UI kits are very helpful to create appealing web apps. You can use the free UI kits as well.
