for Use Recursion to Create a Range of Numbers

We have defined a function named

`rangeOfNumbers`

with two parameters. The function should return an array of integers which begins with a number represented by the`startNum`

parameter and ends with a number represented by the`endNum`

parameter. The starting number will always be less than or equal to the ending number. Your function must use recursion by calling itself and not use loops of any kind. It should also work for cases where both`startNum`

and`endNum`

are the same.

I came up with

```
function rangeOfNumbers(startNum, endNum) {
if (endNum - startNum === 0) {
return [startNum];
} else {
var numbers = rangeOfNumbers(startNum + 1, endNum);
numbers.push(startNum);
return numbers;
}
}
```

it didn’t work. so I went to the guide and looked at the solution to see what I was missing.

the given solution was

```
function rangeOfNumbers(startNum, endNum) {
if (endNum - startNum === 0) {
return [startNum];
} else {
var numbers = rangeOfNumbers(startNum, endNum - 1);
numbers.push(endNum);
return numbers;
}
}
```

how are those different? what do the actual outcomes look like?

Thank you in advanced.
