An interviewer will be very interested in your ability to use debugging tools to optimize a website's performance. Having an appealing website that attracts visitors is only the first step in the process. If the website underperforms or doesn't provide the information the visitors are interested in, they will stop using it. The interviewer wants to make sure that you are familiar with the debugging tools and have a structured framework to analyze and optimize a website's performance.

"Even the best-designed websites have performance issues from time to time. Identifying the root cause of these and resolving them is critical to my work as a web developer. When I notice that the website's performance is degrading, I first identify the underperforming elements. I then inspect them visually to see if I can spot any obvious errors in the code. Once this step is complete, I use standard debugging tools to identify errors that I cannot see. I typically use some of the common ones, including Angular.JS, Sass, Grunt, Sentry, GDB, and NPM."
