Given an array of `points` where points[i] = [xi, yi] represents a point on the **X-Y** plane, return _the maximum number of points that lie on the same straight line_.

**Example 1:**

**Input:** points = [[1,1],[2,2],[3,3]]

**Output:** 3 

**Example 2:**

**Input:** points = [[1,1],[3,2],[5,3],[4,1],[2,3],[1,4]]

**Output:** 4 

**Constraints:**

*   `1 <= points.length <= 300`
*   `points[i].length == 2`
*   -104 <= xi, yi <= 104
*   All the `points` are **unique**.
