on my iPhone 6 Plus with the latest iOS, the above page keeps crashing to the extent of the page becoming entirely unusable.

it works fine on my iPad Mini, aside from the effects being very laggy.

UPDATE: actually it's also crashing on the iPad, just much less frequently.

On my iPhone this first shows up on branch "step-5". It doesn't occur for steps 1 to 4.

Thanks for the feedback, we will look into this.

I think the lag is really just because it was not best designed for a phone. We are listening to click events in the tutorial which feels laggy on mobile (touchstart gives a smoother feel). Also, the duration of the animation is too long for a skinny screen.

I think any lag is just because of jit compilation in the end.

In regards to the crashing I have been unable to duplicate but will continue to look into it.

I can reproduce this almost every time on my iPhone 5 running iOS 8.3.
Replacing getRandomMessage() with a hard-coded string makes it run without errors.

On line 16 of Tweet.js:
setContent('this is a message'); //getRandomMessage());
