List all the file paths!

path-finder.js

// Given a certain object that represents a file system, create a function that
// returns the path to every file in the system.

// Assumptions:
// * All keys are valid paths with a trailing slash.
// * Values of keys can either be objects that represent folders, or they can be
//   an array of files.
// * Every path terminates in an array containing a single file or multiple files.
var path = {
    '/': {
        'Users/': {
            'Josh/': {
                'Documents/': {
                    'Pictures/': ['pic1.jpg', 'pic2.jpg']
                }
            },
            'David/': {
                'Games/': ['League of Legends']
            }
        }
    }
};

console.log(yourFunction( /* params */ ));

// Result:
//   [ '/Users/Josh/Documents/Pictures/pic1.jpg', 
//     '/Users/Josh/Documents/Pictures/pic2.jpg'
//     '/Users/David/Games/League of Legends' ]
