/**
 * Creates a function that performs a partial deep comparison between a given
 * object and `source`, returning `true` if the given object has equivalent
 * property values, else `false`. The created function is equivalent to
 * `_.isMatch` with a `source` partially applied.
 *
 * **Note:** This method supports comparing the same values as `_.isEqual`.
