So I have the following code for this challenge: function getIndexToIns(arr, num) { arr.sort((a, b) => a - b) console.log(arr); for (let i = 0; i < arr.length; i++){ if (num === arr[i]){ return arr.indexOf(num); } else if(num < arr[i]){ arr.spli…

If the array is empty what is the lowest index? There are not many options. Regarding switch you can use it in functions.

zero right? but doesnt arr.length === 0 imply the array is empty?

Yes, the array is empty. So the number you are going to add will be the first one, i.e. at the index 0.

correct. but am I wrong to skip the adding or using “push” method and just return 0? im getting undefined when I enter either of the below codes: else if (arr.length === 0){ return 0; } else if (arr.length === 0){ arr.push(num); return arr.indexOf(num)…

Because if array is empty your for loop doesn’t execute.

thank you!! function getIndexToIns(arr, num) { arr.sort((a, b) => a - b) if (arr && arr.length <= 0){ arr.push(num); return arr.indexOf(num); } else { for (let i = 0; i < arr.length; i++){ if (num === arr[i]){ return arr.indexOf(num)…

Why not just pull the condition out of the for loop to the top of the function just after the sort method.

Never mind. You did that already. I was just wondering why u did if arr and i am not sure the length can be less than zero - an empty array will return true… Seems redundant
