Treehouse TeacherHi there, Trenton! First, kudos on picking up on the const
! But this makes the object immutable. The properties inside them are specific to that object. She touches on this in the first video around 0:38.
Properties are like object specific variables that store information.
You can change the values of the properties, but you cannot overwrite the entire object. For instance you couldn't later do this:
ernie = [1, 2, 3];
It won't allow for you to change the object itself, but the properties inside them (and even the methods) are like variables that are specific to that object.
Hope this helps!
