This page contains an optimizing BF interpreter
programed with JavaScript.
For it to work JavaScript has to be enabled.
Below, you can enter an BF program,
and then execute it by pushing the `Execute' button. If you want a
trace of all the executed statements,
then push the `Execute-trace' button. If the program you entered
is a Constant Number BF program you can us any
of the `CN-execute' buttons. The calculated constant number will be
printed in the output window.
If you press the `compile to c' button, than a C program will appear
in the text area at the bottom of the page.
Another online BF interpreter can be found under
the name BrainOS.
