| // Filter Range "In place" | |
| // Write a function filterRangeInPlace(arr, a, b) that gets an array arr and | |
| // removes from it all values except those that are between a and b. The test is: a ≤ arr[i] ≤ b. | |
| // !! The function should only modify the array. It should not return anything. | |

| if ((arr[i] < a || arr[i] > b)) { | |

| i--; | |
| } | |
| } | |
| } | |
| let arr = [5, 3, 8, 1]; | |
| filterRangeInPlace(arr, 1, 4); // removed the numbers except from 1 to 4 | |
