title: How much memory does one array-element take?
body: <p>I think there can be a difference between browers,</p>
  
  <p>but how do I find out how much memory an array or one element of it takes in Javascript?</p>
  
  <p>I want to figure out how much space I save when using a typed array.</p>
  
  <p>Thanks in advance!</p>
