Easily handle defaults for your options

npm install defaults

import defaults from 'defaults';
const calculate = options => {
	options = defaults(options, {
		timeout: {
			before: 100,
			after: 100
		}
	});
	console.log(options);
	//=> {timeout: {before: 200, after: 100}}
	// …
}
// …
calculate({timeout: {before: 200}});

The given parameters are deep-cloned and never mutated.

If the value is not a plain object, a new plain object will be used instead.
