Clymer-DeBellis Javascript Benchmark

Back in the days of the Apple II+, the Commodore 64 and the Atari 800, we would scientifically test computer speed by entering an empty FOR-NEXT loop in BASIC. As I recall, 10,000 iterations would take about 10 seconds. Or maybe it was 1000 iterations.

Anyway, today's commonly-available interpreted language is JavaScript. On my creaky, old Macintosh Performa I can whip through 100,000 iterations of an empty FOR loop in about a second. This just seems to show the truth of Manfred Low's postulate: "Computers seem to be getting faster, but let's go out and get a Data General with punched paper tape input."

Let me know of your results: Email.
