Convert a camelized/dasherized/underscored string into a humanized one: `fooBar-Baz_Faz` → `Foo bar baz faz`

import decamelize from 'decamelize';

export default function humanizeString(string, options = {}) {

		throw new TypeError('Expected a string');
	}

	if (!options.preserveCase) {

	string = string.replace(/[_-]+/g, ' ').replace(/\s{2,}/g, ' ').trim();
	string = string.charAt(0).toUpperCase() + string.slice(1);
