Problem Script:

function repeat(str, num) {
  // repeat after me
  return str;
}

repeat('abc', 3);

Explanation:

The program is very simple, we have to take a variable and return that variable being repeated certain amount of times. No need to add space or anything, just keep repeating it into one single string.

Hint: 1

You can't edit strings, you will need to create a variable to store the new string.

Hint: 2

Create a loop to repeated the code as many times as needed.

Hint: 3

Make the variable created store the current value and append the word to it.

My code:

function repeat(str, num) {
    var accumulatedStr = "";
    while (num > 0) {
        accumulatedStr += str;
        num--;
    }
    return accumulatedStr;
}

My Code Explanation:

• Create a variable to store the repeated word.
• Use a while loop or for loop to repeat code as many times as needed according to num
• The we just have to add the string to the variable created on step one. and increase or decrease num depending on how you set the loop.
• At the end of the loop, return the variable for the repeated word.
