|
* 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` |

* @param {Array|string} path The path of the property to get. |

|

|
* var objects = [ |
|
* { 'a': 1, 'b': 2, 'c': 3 }, |
|
* { 'a': 4, 'b': 5, 'c': 6 } |

* ]; |

|
* _.find(objects, _.matchesProperty('a', 4)); |
|
* // => { 'a': 4, 'b': 5, 'c': 6 } |
|
* |
|
* // Checking for several possible values |
|
* _.filter(objects, _.overSome([_.matchesProperty('a', 1), _.matchesProperty('a', 4)])); |
|
* // => [{ 'a': 1, 'b': 2, 'c': 3 }, { 'a': 4, 'b': 5, 'c': 6 }] |
