This is a quick exploration of how to use Edge Dev Tools to investigate JavaScript execution time issues. We’ll quickly run a performance profile and identify what part of the JavaScript is the “most responsible” for any performance issues. The idea is to show just the quickest way to find the source of an issue,Continue reading “Investigate JavaScript Execution Times Using Edge Dev Tools”
