Probably not-so-coincidentally, I have almost the same search url saved in
notes I'm preparing for discussion at the next TC39 meeting. If you remove
the "Math." part, there are 20,288 more matches:*2%22&type=Code&ref=searchresults if you
add spaces between PI, *, 2 there are over 3000 more matches. When the
parts of the term are flipped around as "2*PI":*PI%22&type=Code&ref=searchresults (137,134
matches for those that don't want to click). Then variations of "math.PI",
"Math.PI" with or without spaces will yield several thousand more for each.

Just because other languages don't include a TAU constant doesn't mean
ECMAScript cannot.

Just because "serious mathematicians" think this is "crackpot territory",
doesn't mean it's not useful (the condescension of that claim certainly
