## Description
Return the lowest index at which a value (second argument) should be inserted into an array (first argument) once it has been sorted. The returned value should be a number.
For example, getIndexToIns([1,2,3,4], 1.5) should return 1 because it is greater than 1 (index 0), but less than 2 (index 1).
Likewise, getIndexToIns([20,3,5], 19) should return 2 because once the array has been sorted it will look like [3,5,20] and 19 is less than 20 (index 2) and greater than 5 (index 1).
Remember to use Read-Search-Ask if you get stuck. Write your own code.

## Challenge Seed
```js
function getIndexToIns(arr, num) {
// Find my place in this sorted array.
return num;
}
getIndexToIns([40, 60], 50);
```
## Solution
```js
function getIndexToIns(arr, num) {
arr = arr.sort((a, b) => a - b);
for (let i = 0; i < arr.length; i++) {
if (arr[i] >= num) {
return i;
}
}
return arr.length;
}
getIndexToIns([40, 60], 50);
