Instructions

Write a Befunge-93 interpreter createBefungeApplication in JavaScript that will, given an initial string of Befunge source code, return a function that will run the Befunge code every time it is called, with the parameters acting as the program's input.

Keep in mind that Befunge applications can modify their own source code, which stays modified for successive program executions.

function createBefungeApplication(originalSourceCode){ /* ... */ }

const guessingGameSource = 'v >$>  v <>0v\n4>|v?v#?#^?8v\n4!8123    9 1\ng-4>>>># >>1v\n:**v <4>5^v<+\n84-p 4^?6^\9:\n>^&& 4 >7^%58\nv:<< ^+*  <^<\n>." si",,,-:v\nv"correct!"<!\n8>"wol ",,v|<\n2|,,,"too"  <\n9 >:#,_@#:<`!\n\> "hgih "^>^\n>#^/#p*#44#4_';

const makeGuess = createBefungeApplication(guessingGameSource);

console.log(makeGuess(5)); // 5 is too low
console.log(makeGuess(8)); // 8 is too high
console.log(makeGuess(7)); // 7 is correct!

console.log(makeGuess(7)); // 7 is too high
console.log(makeGuess(3)); // 7 is too high
console.log(makeGuess(1)); // 7 is correct!

//  ... and so on
