function isMatch(object, source) {
      return object === source || baseIsMatch(object, source, getMatchData(source));
    }
Performs a partial deep comparison between `object` and `source` to
determine if `object` contains equivalent property values.

**Note:** This method is equivalent to `_.matches` when `source` is
partially applied.

Partial comparisons will match empty array and empty object `source`
values against any array or object value, respectively. See `_.isEqual`
for a list of supported value comparisons.

@param {Object} object The object to inspect.
@param {Object} source The object of property values to match.
@returns {boolean} Returns `true` if `object` is a match, else `false`.
@example

var object = { 'a': 1, 'b': 2 };

_.isMatch(object, { 'b': 2 });
// => true

_.isMatch(object, { 'b': 1 });
// => false
