Just wanting to know how they got to this solution as the statement they wrote made me think different.

Exercise.

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.

My original solution…

function rangeOfNumbers(startNum, endNum) {

if (startNum <= endNum) {

return ;

} else {

const arr = rangeOfNumbers();

arr.push(startNum, endNum);

return arr;

}

};

console.log(rangeOfNumbers(1, 10));

Correct solution…

function rangeOfNumbers(startNum, endNum) {

if (endNum - startNum === 0) {

return [startNum];

} else {

var numbers = rangeOfNumbers(startNum, endNum - 1);

numbers.push(endNum);

return numbers;

}

}
