title: Are variable length arrays possible with Javascript
body: <p>I want to make a variable length array in Javascript.</p>
  
  <p>Is this possible. A quick google search for "Javascript variable length array" doesn't seem to yield anything, which would be surprising if it were possible to do this.</p>
  
  <p>Should I instead have a String that I keep appending to with a separator character instead, or is there a better way to get a varible length array-like variable.</p>
