There was a problem hiding this comment.
Please change the first logged message to
log.push(`Initial value of ${propName} set to ${to}`);
and update the image. Otherwise, LGTM

We weren't checking
changedProp.isFirstChange()so for the very first round of change detection,changedProp.previousValuewas a private object belonging to Angular. In 4.x this private object changes to undefined.Since the object itself is private and shouldn't be used, it's more sensible to change the behaviour of the example and test.
