DOMPointReadOnly: w property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

Note: This feature is available in Web Workers.

The DOMPointReadOnly interface's w property holds the point's perspective value, w, for a read-only point in space.

If your script needs to be able to change the value of this property, you should instead use the DOMPoint object.

Value

A double-precision floating-point value indicating the w perspective value for the point. This value is unrestricted, meaning that it is allowed to be infinite or invalid (that is, its value may be NaN or ±Infinity). The default is 1.0.
