		# ts-options-defaults

		`Object.assign({}, defaults, options)` and equivalent with destructing `{...defaults, ...options}` come with a pitfall of creating only a _shallow copy_. Lodash `_.merge` works on deep properties, but it merges arrays and that usually makes no sense in the context of default options (also it mutates first element; this package doesn't). This package fixes that problem - it merges objects deeply, overrides arrays and merges class functions plus the result remains strongly typed.
