The DOMPointInit dictionary's x property is used to specify the x component of a point in 2D or 3D space when either creating or serializing a DOMPoint or DOMPointReadOnly.
In general, positive values x mean to the right, and negative values of x means to the left, assuming that transforms have not altered the orientation of the axes.
Syntax
var DOMPointInit = {
x: xPos
};
DOMPointInit.x = xPos;
var xPos = DOMPointInit.x;
Value
A double-precision floating-point value indicating the point's x coordinate. This value is unrestricted, meaning that it is allowed to be infinite or invalid (that is, its value may be NaN or ±Infinity).
If this property is missing when the DOMPointInit object is passed into fromPoint(), the value is assumed to be 0 by default.
DOMPointInit is used as an input when calling either DOMPointReadOnly.fromPoint() or DOMPoint.fromPoint(), and is returned by the DOMPointReadOnly.toJSON() and DOMPoint.toJSON() methods.
