Thanks!

I didn’t know about this until I’ve found an occurance of “in” inside of Greensock’s TweenMax library. It is used inside the AutoAlphaPlugin class, as seen here:

  _ignoreVisible = Boolean("visible" in lookup);

It’s a very neat shortcut.

PS:
There’s a few places in your article where you’ve mentioned the “is” keyword instead of “in”. Maybe a typo? I’ve highlighted them with square brackets in the quoted parts below.

Quote: “… This can be rewritten with the [is] operator …”
Quote: “… The second two show the usefulness of the [is] operator …”
