--description--

In this lab, you will create a function that repeats a given string a specific number of times. For the purpose of this lab, do not use the built-in .repeat() method.

Objective: Fulfill the user stories below and get all the tests to pass to complete the lab.

User Stories:

1. You should create a function named repeatStringNumTimes that takes two parameters: a string and a number.
2. The function should return the string repeated the specified number of times.
3. If the number is less than or equal to zero, the function should return an empty string.

--hints--

You should create a function named repeatStringNumTimes.

assert.isFunction(repeatStringNumTimes);

repeatStringNumTimes should take two parameters.

assert.lengthOf(repeatStringNumTimes, 2);

The function repeatStringNumTimes should always return a string.

assert.isString(repeatStringNumTimes('hello', 3));

repeatStringNumTimes("*", 3) should return the string ***.

assert.strictEqual(repeatStringNumTimes('*', 3), '***');

repeatStringNumTimes("abc", 3) should return the string abcabcabc.

assert.strictEqual(repeatStringNumTimes('abc', 3), 'abcabcabc');

repeatStringNumTimes("abc", 4) should return the string abcabcabcabc.

assert.strictEqual(repeatStringNumTimes('abc', 4), 'abcabcabcabc');

repeatStringNumTimes("abc", 1) should return the string abc.

assert.strictEqual(repeatStringNumTimes('abc', 1), 'abc');

repeatStringNumTimes("*", 8) should return the string ********.

assert.strictEqual(repeatStringNumTimes('*', 8), '********');

repeatStringNumTimes("abc", -2) should return an empty string ("").

assert.isEmpty(repeatStringNumTimes('abc', -2));

repeatStringNumTimes("abc", 0) should return "".

assert.isEmpty(repeatStringNumTimes('abc', 0));

The built-in repeat() method should not be used.

assert.notMatch(__helpers.removeJSComments(code), /\.repeat/g);

--solutions--

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

repeatStringNumTimes('abc', 3);
