Challenge: Assigning the Value of One Variable to Another

Link to the challenge:

Hey, in this one you don’t actually have to make two seperate assignments. Above your code you can see a = 7, by making b equal to a then you are also fulfilling he second test which is to make b equal to 7.

I also seen you’ve re-declared var a once a variable has been declared in this way (which it has already been above) then you can reference the variable by simply using it’s name, in this case a.

Hope this helps.
