Today I learned: prop.children

A simple example

Here’s an example of a stateless function that is used to create a component. Again, since this is a stateless function, there is no 'this' keyword so just use props.children

const Picture = (props) => {
return (
<div>
<img src={props.src}/>
{props.children}
</div>
)
}

This component contains an <img> that is receiving some props and then it is displaying {props.children}.

Whenever this component is invoked {props.children} will also be displayed and this is just a reference to what is between the opening and closing tags of the component.

//App.jsrender () {
return (
<div className='container'>
<Picture key={picture.id} src={picture.src}>
//what is placed here is passed as props.children
</Picture>
</div>
)
}

Instead of invoking the component with a self-closing tag <Picture /> if you invoke it will full opening and closing tags <Picture> </Picture> you can then place more code between it.

This de-couples the <Picture> component from its content and makes it more reusable.
