title: Declaring vs Initializing a variable?
body: <p>I'm curious to know the difference between declaring a variable, and initializing a variable. e.g.</p>
  
  <pre><code>var example; // this is declaring
  
  var example = "hi" // initializing? Or just "adding a value"?
  </code></pre>
  
  <p>I don't think I'm right there, but what exactly is the definition of each? Or do they basically mean the same thing?</p>
