  Example.componentWillUpdate(): void
Called immediately before rendering when new props or state is received. Not called for the initial render.

Note: You cannot call 
{@link 
Component.setState
}
 here.

Note: the presence of 
{@link 
NewLifecycle.getSnapshotBeforeUpdate
getSnapshotBeforeUpdate
}

or 
{@link 
StaticLifecycle.getDerivedStateFromProps
getDerivedStateFromProps
}
 prevents
this from being invoked.
@deprecated16.3, use getSnapshotBeforeUpdate instead; will stop working in React 17@see{@link https://legacy.reactjs.org/blog/2018/03/27/update-on-async-rendering.html#reading-dom-properties-before-an-update}@see{@link https://legacy.reactjs.org/blog/2018/03/27/update-on-async-rendering.html#gradual-migration-path}componentWillUpdate() {

    //   - Do not call `this.setState` in `componentWillUpdate` outside of functions, such as callbacks.
