As we know, we can give, or assign, values to variables at any time. There are some values that we want to make permanent, though: constants.

Constants are variables that declared in capitals. How would you go about making my name a constant?

Yes! Now my name is a constant, and if we try to change it, Ruby will kindly warn us that its value is permanent.

That's not very permanent, is it? I thought we agreed that my name would be a constant?
