Accessing React component children props from the parent

Because the links in the comments are broken, I enclose a link to the current react-router Switch module implementation where children are parsed (see the render() function). Also in this tutorial video the author accesses children props from parent.

To not bump into the same problem with link expiring again, here is how the code for accessing children props from parent would look like for above example when inspired by react-router‘s Switch:

(inside GameObject)

const { children } = this.props

React.Children.forEach(children, element => {
  if (!React.isValidElement(element)) return

  const { source } = element.props

  //do something with source..
