ECMAScript
Scripting language introduced by the Netscape corporation in 1996 as JavaScript, leeching onto the hype that surrounded Java at the time the language took its name from it but has no other connection with Java at all. EMCAScript is a loosely LISP inspired tool and despite its enormous popularity is considered one of the worst designed programming languages to ever escape into the wild and the only such horror story to gain any popularity since PEARL. The classic example of how little forethought was used when cobbling the language together is that despite being released just over three years before the 1999/2000 turnover the first versions of the language were not year 2000 ready, resulting in a few set-top Internet access boxes that used Netscape starting to have odd failures on some webpages in 2000 despite being less than 2 years old.
