You mention that the Map object has a contains method, but I don't see that listed at https://developer.mozilla.o... and testing it in play.js doesn't seem to work. Was this removed or am I missing something?

Hey Arber,

Thanks for sharing this. Though, you sent a link about .has() method, so contains() is still does not exist. ;)

Cheers!

Yo J.R. Jenkins!

Woh! This is a mystery... even to me! You're absolutely right - this method does not exist... and unfortunately, I can't even remember what the heck I was thinking or where this came from!? It was not removed, it was just simply not ever there :). We'll edit that out of the video - very good catch! I'm glad you challenged us on that :).

Cheers!

Hey Ryan!

No problem, but worry about that edit after you finish the Web Pack Series!! :-) I am on the edge of my seat following along at that one as you have really demystified some aspects of Web Pack that I just couldn't wrap my head around before.

As always thanks for the great tutorials.

Ah, awesome! I have *loved* writing the Webpack tutorial. We'll keep having a new piece out each day :).

Cheers!

This tutorial uses Symfony 3. But, since this is a JavaScript tutorial, all the concepts work fine in newer versions of Symfony.
