I probably could have worded it differently, but I&#x27;m not upset about it, it just makes me sad that people might not know that these tools exist!<p>I often use the same kind of thing for debugging (console.log(&#x27;got here&#x27;)) because it&#x27;s sometimes too much work to leave the code to just get an understanding of if something is hit or not.<p>When i started reading the article i was really hoping he would use the profiling tools. I just feel sad that they are being overlooked a lot of the time, and this is a textbook perfect use case for it!
