## Description
<section id='description'>
In JavaScript, you can store a value in a variable with the <dfn>assignment</dfn> operator (<code>=</code>). 
<code>myVariable = 5;</code>
This assigns the <code>Number</code> value <code>5</code> to <code>myVariable</code>.
If there are any calculations to the right of the <code>=</code> operator, those are performed before the value is assigned to the variable on the left of the operator.

```js
var myVar;
myVar = 5;
```

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