title: Point.flipX()
---
A point's `flipX()` method returns a new `Point` that mirrors the original point around the X-value of the point you pass it.
If you do not pass in a point, it will default to mirroring around an X-value of zero.
The `Point.flipX()` method returns a new `Point` that mirrors the original
