Why does Phaser.Sprite.play have its own framerate?

Why does Phaser.Sprite.play take in a framerate as a variable, separate from the game's actual framerate? 

I am trying to load a spritesheet of a walking animation, and it run as I hold an arrow key, but I'm confused why the playing of the animation would require a framerate to be set, separate from how fast the game itself is running? Wouldn't this result in strange differences when viewing the animation, if the engine happens to run below a certain framerate?

To load a walking sprite animation, should I be using the `.play` method? Should I instead be ticking the frames myself in the game loop?

Those frames are the frames (cells) of the spritesheet. See examples/v2/animation/animation-events.

The mummy spritesheet has 18 frames and is played at 10 frames per second, so it loops every 1.8 seconds.

Like @samme said, it just allows you to fine-tune your animation speed. It has nothing to do with the game framerate.
