5,290 PointsChanging the value of a constant
We learned in past lessons that a value of object instantiated with "let" keyword can't be changed. It would be a constant.
But in this lesson, we initialised toy with "let" and after, we changed the value of "batteries" property.
Why can we change the value of the toy's property if it is instantiated with "let'?
let toy = Electronic(title: "RC Car", price: 79)
toy.batteries = true

You are right, one can't change the value of a constant but while you can't assign another object to the constant toy
you can still make use of all the properties of this (constantly assigned) object :)

5,290 PointsThanks, Holger. I hadn't realised that the fact that an object is constant does not automatically apply to its properties.
