--description--

In JavaScript, you can store a value in a variable with the assignment operator (=).

myVariable = 5;

This assigns the Number value 5 to myVariable.

If there are any calculations to the right of the = operator, those are performed before the value is assigned to the variable on the left of the operator.

var myVar;
myVar = 5;

First, this code creates a variable named myVar. Then, the code assigns 5 to myVar. Now, if myVar appears again in the code, the program will treat it as if it is 5.

--instructions--

Assign the value 7 to variable a.

--hints--

You should not change code above the specified comment.

assert(/var a;/.test(__helpers.removeJSComments(code)));

a should have a value of 7.

assert(typeof a === 'number' && a === 7);

--before-user-code--

if (typeof a != 'undefined') {
  a = undefined;
}

--after-user-code--

(function(a){return "a = " + a;})(a);

--seed-contents--

// Setup
var a;

// Only change code below this line

--solutions--

var a;
a = 7;
