Challenge: Basic JavaScript - Understanding Uninitialized Variables

Link to the challenge:

You are supposed to initialize the variables. Instead you declared each variable and assigned a value to them in separate statements. Initializing means assigning a value at the same time as when the variable is declared. Try to reset the challenge and try again.

note that the " i am a " string part is not there as it should be.
