Debugging and troubleshooting in Javascript: Tips and tricks
I’m a Software Developer with a strong foundation in building scalable, accessible, and inclusive products across both early-stage startups and enterprise environments. My experience spans backend-heavy systems, real-time data pipelines, and internal tooling that drives measurable impact.
I currently work at WorkIndia as a Software Development Engineer, where I help design and build robust backend systems, real-time data pipelines, and automation tools that power one of India’s largest job platforms. Previously, I interned at Microsoft and Raven (YC S22), where I contributed to building end-to-end, production-ready features that significantly improved product performance and operational efficiency.
Outside of work, I’m building Evolv, a fitness app designed to go beyond tracking, helping users build intentional workout rituals backed by meaningful insights. It’s been an exciting journey bringing product thinking and engineering together to solve a deeply personal problem.
🧠 Leadership & Mentorship Mentoring junior developers and interns, helping them grow technically and align with real-world engineering best practices.
💡 Community & Communication Beyond code, I’m a people-first engineer. I’ve led developer communities, such as the Google Developer Student Club at university, scaling it to over 2,000 members. I’ve spoken at tech events and enjoy sharing ideas, whether through talks or writing. I also maintain a blog where I explore both the technical and human side of software development.

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.
