Solution to Sub-task: Get Nested Path Name

var getNestedPathNames = async (dir) =>{
	var dirNames = await getPathNames(dir);
	if (dirNames.length === 0) return [];
	var nestedPathPromises = dirNames
		.map(x => getNestedPathNames(x));
	var nestedPath = await Promise.all(nestedPathPromises);
	var newPath =  nestedPath.reduce((prev, curr)=> [...prev,...curr], []);
	return [...dirNames, ...newPath];
}
var test = async () => {
	await populate_directory(); // initialise custom directories in background
	var names = await getNestedPathNames('dir'); // get nested paths
	console.log(names); // print output of promise
}
test();
