--description--

In JavaScript, you can store a value in a variable with the <dfn>assignment</dfn> 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);
