/*
	Pattern Master
	
	create a function patternMaker() that takes two arguments: an integer n and a piece of data of any type. patternMaker() should return an array of the second argument, repeated n times
	
	ex)
		patternMaker(5, 'Boo') --> ['Boo', 'Boo', 'Boo', 'Boo', 'Boo']
		patternMaker(3, ['cat', 'dog']) --> [['cat', 'dog'], ['cat', 'dog'], ['cat', 'dog']]
*/

function patternMaker(n, item) {
	var returnArr = [];
	for (var i = 0; i < n; i++) {
		returnArr.push(item);
	}
	return returnArr;
}


console.log(patternMaker(5, 'Boo'));
// ['Boo', 'Boo', 'Boo', 'Boo', 'Boo'])
console.log(patternMaker(3, ['cat', 'dog']));
// [['cat', 'dog'], ['cat', 'dog'], ['cat', 'dog']])
