javascript selector performance

JavaScript Selector Performance | Go Make Things

One of the students in my Vanilla JS Slack channel asked me about the performance difference between querySelector() and things like getElementById() and getElementsByClassName(). Specifically, getElementById() and getElementsByClassName() are more than twice as fast as querySelector() and querySelectorAll(). So, thatโ€™s bad, right? I honestly donโ€™t think it matters. getElementById() can run about 15 million operations a second, compared to just 7 million per second for querySelector() in the latest version of Chrome.
