Function bisectLeft

bisectLeft(sorted_arr: (number | bigint)[], target: number): number
Locates the insertion point for target in sorted_arr to maintain sorted order. If target is already present, the insertion point is to the left of any existing entries.
Parameters
- sorted_arr: (number | bigint)[]
  The sorted array to search. Must be sorted in ascending order.
- target: number
  The value to locate.
Returns number
The index where target should be inserted.
Remarks
- The time complexity is O(log n).
- If the array is not sorted, the result is undefined.
- This corresponds to Python's bisect_left.
Example
```
const arr = [1, 2, 4, 4, 6;
bisectLeft(arr, 4); // Returns 2
bisectLeft(arr, 3); // Returns 2
```
