What is the shortest and simplest Javascript implementation and where can I

There may be. Many of my pages call little or no JavaScript during
load, but use input type=text to set up a calculation and input
type=button to start it. The ange of times that the calculation is
expected to take is from "too fast to see" to *millennia*. Somewhere
in between, speed matters.

You may wonder why there should be code that takes millennia. The
answer is that in a good browser it takes millennia, in a bad one a
few minutes. In this specific case, IE and Firefox are good, Chrome
is bad, Opera and Safari are not so bad, and are expected to take
hours. See js-randm.htm "Repeat Interval".

Verifying the Date of Easter or ISO Week Numbers, each over the full
repeat range, provide other examples where computation speed matters.
