Brainfuck interpreter in javascript
I got bored today and decided to make a brainfuck interpreter with javascript. After I was done I did a quick google search to see what other people did for a js solution to compare and constrast however I couldn't find anything with less than 100 lines (to be fair others had more features such as step debugging and config options).   So here I present my rather naive (but small) version in 17 lines of javascript, 328 bytes manually minified.   function bf(code, input){     var src = "var ptr = 0, inptr = 0, output = '', data = new Uint8Array(30000);",         op = {             '>': '++ptr;',             '  ...and some samples...  // hello world bf('++++++++[>++++[>++>+++>+++>+ +>+>->>+[ >.>---.+++++++..+++.>>. >+.>++.') // echo input bf(',[.,]', 'input') // echo reverse input bf(',[>,]   Here's a link to a live sample.
