Challenge: Declare a Read-Only Variable with the const Keyword

Link to the challenge:

you didn’t declare the variable Fact.

It is “freeCodeCamp” with a lower case f and not “FreeCodeCamp” with uppercase F.
You just need to case of the constant. Changing the string within the quotes can fail the test.
