+
+_Difficulty: Beginner_
+
+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).

+#### Solution 1
+
+```js
+function getIndexToIns(arr, num) {
+  arr.sort((a, b) => a - b);
+
+  for (let i = 0; i < arr.length; i++) {
+    if (arr[i] >= num) return i;
+  }
+  return arr.length;
+}
+
+getIndexToIns([10, 20, 30, 40, 50], 35);
+```
+
+#### Solution 2
+
+```js
+function getIndexToIns(arr, num) {
+  return arr.filter((val) => num > val).length;
+}
+
+getIndexToIns([10, 20, 30, 40, 50], 35);
