--description--

After a value is assigned to a variable using the <dfn>assignment</dfn> operator, you can assign the value of that variable to another variable using the <dfn>assignment</dfn> 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(__helpers.removeJSComments(code)) && /a = 7;/.test(__helpers.removeJSComments(code)) && /var b;/.test(__helpers.removeJSComments(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(__helpers.removeJSComments(code)));
