* Creates a function that performs a partial deep comparison between the
|
|
* value at `path` of a given object to `srcValue`, returning `true` if the
|
|
* object value is equivalent, else `false`.
|
|
*
|
|
* **Note:** Partial comparisons will match empty array and empty object
|
|
* `srcValue` values against any array or object value, respectively. See
|
|
* `_.isEqual` for a list of supported value comparisons.
|
|
*
|
|
* **Note:** Multiple values can be checked by combining several matchers
|
|
* using `_.overSome`
