What Framerate Does snap! run at?

I'm trying to recreate NES Tetris in snap. I would like to know what framerate snap runs at in order to more accurately emulate NES Tetris.


Snap uses requestAnimationFrame() to sync.
According to the

The number of callbacks is usually 60 times per second, but will generally match the display refresh rate in most web browsers as per W3C recommendation ...

So basically 60 frames per second. Thanks!
