JS Brainfuck Interpreter
Brainfuck, if you didn't know, is an aptly named esoteric programming language.
They say it messes with your mind because there's only a couple
characters you can use to make your program:
[],.<>+-
In a nutshell, the "memory" consists of an infinite array of integers
(each ranging from 0-255). There is a "pointer" which resides somewhere
along this memory strip. ">
" moves the pointer one to the right
while "<
" moves the pointer one to the left. You can
increment and decrement the integer currently at the pointer with
"+
" and "-
". "[
" and "]
"
is a looping mechinism, ".
" prints the ascii value of
the integer currently at the pointer, and ",
" prompts
for input.
In other words, loads of fun! Check it out:

move pointer right<
move pointer left[
jump past matching bracket if value at pointer is zero]
jump to matching bracket if value at pointer is nonzero+
increase value at pointer by 1-
decrease value at pointer by 1.
print value at pointer as character,
take input and store at pointer location-[.-]
