# Repeat a String Repeat a String
---
## Problem 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.

## Hints
### Hint 1
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 2
You can't edit strings, you will need to create a variable to store the new string.
### Hint 3
Create a loop to repeat the code as many times as needed.
### Hint 4
Make the variable created store the current value and append the word to it.

## Solutions
Solution 1 (Click to Show/Hide)
```js
function repeatStringNumTimes(str, num) {
var accumulatedStr = "";
while (num > 0) {
accumulatedStr += str;
num--;
}
return accumulatedStr;
}
```
#### Code Explanation
* 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.

Solution 2 (Click to Show/Hide)
```js
function repeatStringNumTimes(str, num) {
if (num < 1) {
return "";
} else if (num === 1) {
return str;
} else {
return str + repeatStringNumTimes(str, num - 1);
}
}
```
#### Code Explanation
* 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.

```js
function repeatStringNumTimes(str, num) {
return num > 0 ? str.repeat(num) : "";
}
repeatStringNumTimes("abc", 3);
```
#### Code Explanation
* This solution takes a declarative approach.
* It is similar to the third solution, except it uses the ternary operator form of the `if` statement.
