Challenge: Assigning the Value of One Variable to Another

Link to the challenge:

you should not declare a variable more than once and the requirement of the test is to assign a to b without assignment of anything else

The variables are already declared for you, you just need to assign a to b.

var a;
a = 7;
var b;
b = a;

Thank you very much for your help

// Setup

var a;

a = 7;

var b;

b = a;

// Only change code below this line
