The DOMPoint interface's w property holds the point's perspective value, w, for a point in space.
The DOMPoint interface's x property holds the horizontal coordinate, x, for a point in space.
The DOMPoint interface's y property holds the vertical coordinate, y, for a point in space.
The DOMPoint interface's z property specifies the depth coordinate of a point in space.
The matrixTransform() method of the DOMPointReadOnly interface applies a matrix transform specified as an object to the DOMPointReadOnly object, creating and returning a new DOMPointReadOnly object.
Optionalmatrix: DOMMatrixInitThe DOMPointReadOnly method toJSON() returns an object giving the js-nolint toJSON() None.
A
DOMPointobject represents a 2D or 3D point in a coordinate system; it includes values for the coordinates in up to three dimensions, as well as an optional perspective value.MDN Reference
