React pass props to children

import React, { Children, isValidElement, cloneElement } from 'react';

const Child = ({ doSomething, value }) => (
  <div onClick={() => doSomething(value)}>Click Me</div>
);

function Parent({ children }) {
  function doSomething(value) {
    console.log('doSomething called by child with value:', value);
  }

  render() {
    const childrenWithProps = Children.map(children, child => {
      // Checking isValidElement is the safe way and avoids a TS error too.
      if (isValidElement(child)) {
        return cloneElement(child, { doSomething })
      }

      return child;
    });

    return <div>{childrenWithProps}</div>
  }
};

ReactDOM.render(
  <Parent>
    <Child value="1" />
    <Child value="2" />
  </Parent>,
  document.getElementById('container')
);
