Here's example of just throw:

https://github.com/mhulse/get-tile-url/blob/f79b35889e0ad43fda12053cd1d2a1dcd8ef3b61/index.js#L90

	if (this.options.orange == 'orange') {

	// Instead of using `writeFile().then()`, use await:
	await fs.writeFile(html, 'Hello world!', 'utf8');

	let result = await fs.readFile(html, 'utf8');

	await fs.unlink(html);

	// Resolve this async function with the result:
	return result;

	} else {

	throw new Error(`Orange isn’t orange, it’s ${this.options.orange}!`);
