Debugging is not an easy task, but you can find various tools online that will help you in spotting errors and bugs at different development stages. The main role of these popular debugging tools is to identify, examine, and fix the errors by locating their cause.
- Postman A console-based debugging and error tracking solution that allows developers to tweak requests and analyze codes. It is compatible with all major operating systems including Windows, Linux, and macOS.
- ESLint A basic tool that identifies and fixes basic syntax problems and catches errors in the code before execution. It allows developers to customize and write their own rules.

Developers write thousands of codes to develop a web-based application. But, hoping everything will go perfectly is the biggest mistake you might make. You might often face difficulties in the production environment, such as the code not working or not behaving in the manner you wanted it to run.
Many issues arise when developers design and develop a project which often frustrates them. Hence, it is recommended to install debugging tools. These tools will help figure out the root cause of the problem, identify its cause, and eliminate the reason behind its unexpected behavior.
But before buying one for your project, make sure to check if the selected tool supports a rigorous testing phase. Under this phase, developers can easily locate where bugs are found.
Also, make sure it includes intelligent debugging utilities and spot errors and bugs faster as and when they crop up.
