It can be frustrating to encounter errors or bugs in your code, but with the right techniques and tools, you can quickly identify and fix issues. In this blog, I'll discuss some of the my personal tips and tricks I use for debugging and troubleshooting in Javascript.
console.log()
The console.log() can come in handy for debugging. It allows you to print messages or variables to the console, which can help you understand what's happening in your code, you can see the value of variables and the flow of execution.
Add Breakpoints
Most modern browsers come with built-in developer tools that allow you to set breakpoints in your code. A breakpoint is a point in your code where the execution will pause, allowing you to inspect variables and step through your code line by line. By using breakpoints, you can pinpoint exactly where the error is occurring and fix it quickly.
Use error messages to your advantage
When your code encounters an error, it will often provide an error message. While these messages can be intimidating, they can also help identify the issue. Take the time to read the error message carefully, and try to understand what it's telling you. Sometimes, the error message will provide you with enough information to fix the issue right away. if nothing works just copy and paste the error message on google the whole wide community of devs is waiting to help you out!!
Use a linter
A linter is a tool that analyzes your code and checks for errors and potential issues. It can help you catch syntax errors, typos, and other mistakes before running your code. By using a linter, you can reduce the amount of time you spend debugging and ensure that your code is clean and error-free.
Use debugging tools and extensions
There are many debugging tools and extensions available for developers. These tools can provide you with additional functionality, such as the ability to inspect variables and track function calls. Some popular tools I use are Chrome DevTools and Visual Studio Code's debugger.
Conclusion
Debugging and troubleshooting are critical skills for any developer. Using the tips and tricks outlined in this blog, you can quickly identify and fix issues in your code, improving your productivity and code quality. With practice and experience, you'll become a master at debugging and troubleshooting.
