What are fragments?
It's common pattern in React which is used for a component to return multiple elements. Fragments let you group a list of children without adding extra nodes to the DOM.
render() {return (<React.Fragment><ChildA /><ChildB /><ChildC /></React.Fragment>)}
There is also a shorter syntax, but it's not supported in many tools:
render() {return (<><ChildA /><ChildB /><ChildC /></>)}
