# FrameWaitForFunctionOptions.polling property
An interval at which the `pageFunction` is executed, defaults to `raf`. If `polling` is a number, then it is treated as an interval in milliseconds at which the function would be executed. If `polling` is a string, then it can be one of the following values:
- `raf` - to constantly execute `pageFunction` in `requestAnimationFrame` callback. This is the tightest polling mode which is suitable to observe styling changes.
- `mutation` - to execute `pageFunction` on every DOM mutation.
**Signature:**
```typescript
interface FrameWaitForFunctionOptions {
polling?: 'raf' | 'mutation' | number;
}
```
