Product Engineering Take Home

Write a bookmarklet that can be run on this page. The bookmarklet should replace the word "spicy" with the word "demo" in the text animation below. This replacement should happen as fast as possible, replace the characters as they are animated in, and ideally be unpercievable to the user. All other words should appear unreplaced/unmodified. setInterval should not be used. Too easy? Try hard mode.
