What is the value of the `Object.length` property in the JavaScript` Object` constructor?

Question

documentation for JavaScript embedded in the global object Objectindicates that

Object.length

It matters 1.

What is the significance of this property and, besides, why is it not accessible to us object.lengthas it is array.length?
