# Environment

## `frameCount`

This variable stores how many frames have been drawn since the sketch (most recently) started.

For example - if the frame rate is set to 60 (which is the default) - after 3 seconds, frameCount = 180 because this is how many frames have been drawn during that time.

## `width`

This variable stores the width of the **canvas in pixels**, not to be confused with the width of the window, `windowWidth`

## `height`

This variable stores the height of the **canvas in pixels**, not to be confused with the height of the window, `windowHeight`

## `windowWidth`

This variable stores the width of the **window**, not to be confused with the width of the canvas `width`.\
This variable changes as the window size changes.
