title: What are the benefits of a closure, and when are they typically used?
body: <p>I'm a web developer, but lots of folks are looking for slightly more advanced skills and understanding closures seems to be at the forefront of this.</p>
  
  <p>I get the whole "execution context creating a reference to a variable that doesnt ever get destroyed" thing, but really, is this some sort of private or static variable implementation in JavaScript? </p>
