# Polling

Determines the method for repeatedly checking a condition, for example, when waiting for a function to return true. 'REQUEST\_ANIMATION\_FRAME' polls on each browser frame.

## Definition

```graphql theme={null}
enum Polling {
  REQUEST_ANIMATION_FRAME
}
```

## Values

### `REQUEST_ANIMATION_FRAME`

Polls by scheduling a new check on each \`requestAnimationFrame\` call. This is synchronized with the browser's rendering cycle.
