Should be used with type annotation or static contextType. ```ts static contextType = MyContext // For TS pre-3.7: context!: React.ContextType<typeof MyContext> // For TS 3.7 and above: declare context: React.ContextType<typeof MyContext> ``` `see` https://reactjs.org/docs/context.html React.PureComponent.context node_modules/@types/react/index.d.ts:479 `Private` `Readonly` handler: `any` `Readonly` props: `Readonly`<`Props`\> & `Readonly`<{ `children?`: `ReactNode` }\> React.PureComponent.props node_modules/@types/react/index.d.ts:504 refs: `Object` `deprecated` https://reactjs.org/docs/refs-and-the-dom.html#legacy-api-string-refs React.PureComponent.refs node_modules/@types/react/index.d.ts:510 state: `Readonly`<`State`\> React.PureComponent.state node_modules/@types/react/index.d.ts:505 `Static` `Optional` contextType: `Context`<`any`\> If set, `this.context` will be set at runtime to the current value of the given Context. Usage: ```ts type MyContext = number const Ctx = React.createContext<MyContext>(0) class Foo extends React.Component { static contextType = Ctx context!: React.ContextType<typeof Ctx> render() { return <>My context's value: {this.context}</> } } ``` `see` https://reactjs.org/docs/context.html#classcontexttype React.PureComponent.contextType node_modules/@types/react/index.d.ts:461 `Optional` UNSAFE_componentWillMount(): `void` Called immediately before mounting occurs, and before `Component#render`. Avoid introducing any side-effects or subscriptions in this method. This method will not stop working in React 17. Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked. `deprecated` 16.3, use componentDidMount or the constructor instead `see` https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html#initializing-state `see` https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html#gradual-migration-path `void` React.PureComponent.UNSAFE_componentWillMount node_modules/@types/react/index.d.ts:717 `Optional` UNSAFE_componentWillReceiveProps(`nextProps`, `nextContext`): `void` Called when the component may be receiving new props.
