CODE EXAMPLE FOR JAVASCRIPT

pass props from child to parent

/* Parent */
	// The Parent creates the function to be used by the Child and
	// whenever the Child calls the function, it is triggered from
	// the Parent.

const Parent = () => {
  const saveProjectFunction = data => {
    // Recieving data(object) from the Child, instead of passing
    // the object to the Child.
    const modData = {
    	id: 1,
      	...data
    }
  	console.log(`From the Parent ${modData}`);
  }
  return(
		<Child onSaveProject={saveProjectFunction}/>
	)
}

// NOTE: YOU CAN'T SKIP INTERMEDIATE COMPONENT
// The way you pass down through each component, is the same way
// You pass up without skipping a component

/* Child */
  // The child basically calls the function from the parent which was
  // pass in as props, but the function lives and is being used in
  // the parent.

const Child = ({ onSaveProject }) => {
  const sendData = () => {
  	const data = {
      	name: "kouqhar",
      	sport: "basketball"
    }
    // Sending the created data(object) to the Parent instead of
    // Recieving data from the Parent.
    onSaveProject(data)
  }
	return(
  		<button onClick={sendData}><button/>
      )
}

// With love @kouqhar
