I wrote this function that takes 2 arguments - the path to an existing file - file, and the newRoot name. The function splits the new path into directories, replaces the first directory in the path to the file with newRoot, , then loops trough all the directories checking if the director exists, and if not creates one:/** * Creates directories for the file in newRoot if not there * @param {String} file - the path to the file * @param {String} newRoot - the new root directory for the file */functions.makeDirectory = (file, newRoot) => {  let dirPath = path.dirname(file);  let directories = dirPath.split('/');  let currentPath = '';  directories[0] = newRoot;  directories.map(directory => {    currentPath = path.join(currentPath, directory);    if(!fs.existsSync(currentPath)) {      fs.mkdirSync(currentPath);    };  });};The string operations here seem a bit redundat, but I can't figure out how to get rid of them. Is there a more optimal solution for this or am I on the right track?Would it increase performance to rewrite the fs function as a promise?
