 The empty set of dependencies, `[]`, means that the effect will only run once when the component mounts, and not on every re-render. The problem is that inside the `setInterval` callback, the value of `count` does not change, because we've created a closure with the value of `count` set to `0` as it was when the effect callback ran. Every second, this callback then calls `setCount(0 + 1)`, so the count never goes above 1.
 
-Specifying `[count]` as a list of dependencies would fix the bug, but would cause the interval to be reset on every change. Effectively, each `setInterval` would get one chance to execute before being cleared (similar to a `setTimout`.) That may not be desirable. To fix this, we can use the [functional update form of `setState`](/docs/hooks-reference.html#functional-updates). It lets us specify *how* the state needs to change without referencing the *current* state:
