 `ReactDOM.findDOMNode` was [deprecated in October 2018 (v16.6.0)](https://legacy.reactjs.org/blog/2018/10/23/react-v-16-6.html#deprecations-in-strictmode). 
 
 We're removing `findDOMNode` because it was a legacy escape hatch that was slow to execute, fragile to refactoring, only returned the first child, and broke abstraction levels (see more [here](https://legacy.reactjs.org/docs/strict-mode.html#warning-about-deprecated-finddomnode-usage)). You can replace `ReactDOM.findDOMNode` with [DOM refs](/learn/manipulating-the-dom-with-refs):

 react-test-renderer is deprecated. A warning will fire whenever calling ReactTestRenderer.create() or ReactShallowRender.render(). The react-test-renderer package will remain available on NPM but will not be maintained and may break with new React features or changes to React's internals.
