I promised a few weeks ago to come back to the Web Performance Group with data on setImmediate usage within Microsoft Edge. Upon examining the data, I found that it required more parsing and analysis because the usage was much higher than I expected. What I discovered was that the usage was much higher in scenarios where setImmediate was guaranteed to be available such as Windows Store applications.
% of Navigations that include a usage of setImmediate * Microsoft Edge browser navigations-4.73% * All instances of edgehtml.dll (including apps)-21.88% -Todd
