`react-autosuggest` had some breaking changes.
Previously Autosuggest was defined with `any` props which meant no type checking was happening.
New definition enables type checking when using `Autosuggest` component.
```
declare class Autosuggest extends React.Component<Autosuggest.AutosuggestProps> {}
```
