// This is what I've been using, pretty straight forward
// It passes the JSON to the children as props
// Of course, you fetch what you will

import React, { Component, Fragment } from 'react';

export class FetchJsonController extends Component

	constructor(props) {
		super(props);
		this.state = {
			data: null,
		};
	}

	componentDidMount() {
		fetch(this.props.src)
			.then(response => response.json())
			.then(data => {
				console.log(data);
				this.setState({ data })
			});
	}

	render() {
		const _data = this.state.data;
		const children = React.Children.map(this.props.children, child => {
			return React.cloneElement(child, {
				jsonData: _data
			});
		});
		return (
			<div>{ children }</div>
		)
	}
}

// This is how it's used
// SomeCompnent will receive the JSON data
<FetchJsonController src="somefile.json">
  <SomeComponent />
</FetchJsonController>

Required Parameters for Functions in JavaScript

 const isRequired = () => { throw new Error('param is required'); };

const hello = (name = isRequired()) => { console.log(`hello ${name}`) };

// These will throw errors
hello();
hello(undefined);

// These will not
hello(null);
hello('David');
The idea here is that it uses default parameters, like how the b parameter here has a default if you don’t send it anything:
function multiply(a, b = 1) {
  return a * b;
}
