// Repeat a String Repeat a String

// Repeat a given string str (first argument) for num times (second argument).
// Return an empty string if num is not a positive number. For the purpose of this challenge, do not use the built-in .repeat() method.

function repeatStringNumTimes(str, num) {
	if (num < 0) return '';
	let result = '';
	for (let i = 0; i <= num - 1; i++) {
		result += str;
	}
	return result;
}

repeatStringNumTimes('abc', 3);

// OR

function repeatStringNumTimes(str, num) {
	var accumulatedStr = '';

	while (num > 0) {
		accumulatedStr += str;
		num--;
	}

	return accumulatedStr;
}

// OR

function repeatStringNumTimes(str, num) {
	if (num < 1) {
		return '';
	} else {
		return str + repeatStringNumTimes(str, num - 1);
	}
}

// OR

// my favourite
function repeatStringNumTimes(str, num) {
	return num > 0 ? str + repeatStringNumTimes(str, num - 1) : '';
}
