--description--
After a value is assigned to a variable using the assignment operator, you can assign the value of that variable to another variable using the assignment operator.
var myVar;
myVar = 5;
var myNum;
myNum = myVar;
The above declares a myVar
variable with no value, then assigns it the value 5
. Next, a variable named myNum
is declared with no value. Then, the contents of myVar
(which is 5
) is assigned to the variable myNum
. Now, myNum
also has the value of 5
.
--instructions--
Assign the contents of a
to variable b
.
--hints--
You should not change code above the specified comment.
assert(/var a;/.test(code) && /a = 7;/.test(code) && /var b;/.test(code));
b
should have a value of 7.
assert(typeof b === 'number' && b === 7);
a
should be assigned to b
with =
.
assert(/b\s*=\s*a\s*/g.test(code));

--before-user-code--
if (typeof a != 'undefined') {
a = undefined;
}
if (typeof b != 'undefined') {
b = undefined;
}
--after-user-code--
(function(a, b) {
return 'a = ' + a + ', b = ' + b;
})(a, b);
--seed-contents--
// Setup
var a;
a = 7;
var b;
// Only change code below this line
--solutions--
var a;
a = 7;
var b;
b = a;
