}
Performs a deep comparison between `object` and `source` to determine if
`object` contains equivalent property values. If `customizer` is provided
it's invoked to compare values. If `customizer` returns `undefined`
comparisons are handled by the method instead. The `customizer` is bound
to `thisArg` and invoked with three arguments: (value, other, index|key).

**Note:** This method supports comparing properties of arrays, booleans,
`Date` objects, numbers, `Object` objects, regexes, and strings. Functions
and DOM nodes are **not** supported. Provide a customizer function to extend
support for comparing other values.

@param {Object} object The object to inspect.
@param {Object} source The object of property values to match.
@param {Function} [customizer] The function to customize value comparisons.
@param {*} [thisArg] The `this` binding of `customizer`.
@returns {boolean} Returns `true` if `object` is a match, else `false`.
@example

var object = { 'user': 'fred', 'age': 40 };

_.isMatch(object, { 'age': 40 });
// => true

_.isMatch(object, { 'age': 36 });
// => false

// using a customizer callback
var object = { 'greeting': 'hello' };
var source = { 'greeting': 'hi' };

_.isMatch(object, source, function(value, other) {
  return _.every([value, other], RegExp.prototype.test, /^h(?:i|ello)$/) || undefined;
});
// => true
