🚩 Remember to use Read-Search-Ask if you get stuck. Try to pair program 👥 and write your own code 📝

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.

• Global String Object

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

try to solve the problem now

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

try to solve the problem now

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

Solution ahead!

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

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

  return accumulatedStr;
}

🚀 Run Code

• Create an empty string variable to store the repeated word.
• Use a while loop or for loop to repeat code as many times as needed according to num
• Then 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.

function repeatStringNumTimes(str, num) {
  if(num < 0)
    return "";
  if(num === 1)
    return str;
  else
    return str + repeatStringNumTimes(str, num - 1);
}

🚀 Run Code

• This solution uses recursion.
• We check if num is negative and return an empty string if true.
• Then we check if it's equal to 1 and in that case we return the string itself.
• If not, we add the string to a call of our function with num being decreased by 1, which will add another str and another.. until eventually num is 1. And return that whole process.

• Functions - Recursion

function repeatStringNumTimes(str, num) {
  return num > 0 ? str.repeat(num) : '';
}

repeatStringNumTimes("abc", 3);

🚀 Run Code

• This solution takes a declarative approach.
• It is similar to the third solution, except it uses the ternary operator form of the if statement.
