A simple javascript befunge-93 runner

2018-01-02

Primarily for my project euler solutions I wrote a small javascript befunge-93 runner (without befunge93 size restrictions, as with most stuff on this site).

The code is note really optimized and will only run on newer browsers, but it's good enough to play a bit around.

Press [Start] to run the code, [Edit] to change the code and change the interpreter speed with the button on the right side of the [Start] button.
