title: How to get scale value using GreenSock Animation Platform (GSAP)
body: <p>I'm using GSAP's TweenMax to scale a div when a user clicks on a button.</p>
  
  <p>However, what I want to do is be able to get the current scale value and/or know how to increment the scale value by say 0.5.</p>
  
  <p>This is how I'm setting the scale when the button is click:
  <code>TweenMax.to(mapContainer, 0.4, { scale: 1.3});</code></p>
  
  <p>So scaled to 1.3 over 0.4 seconds. So what I'm wanting to do is when a user clicks on that button again, it will scale it by an extra 0.5 each time.</p>
