9,805 PointsonReadyStateChange vs readyStateChange? What is the difference?
I am currently looking a the documentation for the onReadtSate change property. https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/onreadystatechange
Is the onReadyStateChange a property that manages the readystatechange event for the XMLHttpRequest Object?
It says in the documentation:
onreadystatechange property contains the event handler (function) to be called when the readystatechange event is fired.
Thank you very much!

The description might make more sense when you look at some sample code. You'll see it gets assigned with either the name of a function, or assigned to an anonymous function that is defined at the same time.

9,805 PointsThank you for your reply. So if I understand, readyStateChange is an event that happens in the DOM when the stateChange changes?
