Interpreter

The Javascript interpreter used to run the algorithms on this wiki is a highly modified versions of the Narcissus Javascript interpreter. It has been updated to run in web browsers and to be much more standards compliant. It has also been rewritten in continuation passing style, so that the interpretation can be paused and controlled by the user.

The Javascript interpreter currently passes 96% of the ECMAScript Language test262 test suite. (The majority of the failures are currently due to “use strict” code.)
