/**
* Checks if `predicate` returns truthy for **any** element of `collection`.
* The function returns as soon as it finds a passing value and does not iterate
* over the entire collection. The predicate is bound to `thisArg` and invoked
* with three arguments: (value, index|key, collection).
*
* If a property name is provided for `predicate` the created `_.property`
* style callback returns the property value of the given element.
*
* If a value is also provided for `thisArg` the created `_.matchesProperty`
* style callback returns `true` for elements that have a matching property
* value, else `false`.
*
* If an object is provided for `predicate` the created `_.matches` style
* callback returns `true` for elements that have the properties of the given
* object, else `false`.
*
* @static
* @memberOf _
* @alias any
* @category Collection
* @param {Array|Object|string} collection The collection to iterate over.
* @param {Function|Object|string} [predicate=_.identity] The function invoked
* per iteration.
* @param {*} [thisArg] The `this` binding of `predicate`.
* @returns {boolean} Returns `true` if any element passes the predicate check,
* else `false`.
* @example
*
* _.some([null, 0, 'yes', false], Boolean);
* // => true
*
* var users = [
* { 'user': 'barney', 'active': true },
* { 'user': 'fred', 'active': false }
* ];
*
* // using the `_.matches` callback shorthand
* _.some(users, { 'user': 'barney', 'active': false });
* // => false
*
* // using the `_.matchesProperty` callback shorthand
* _.some(users, 'active', false);
* // => true
*
* // using the `_.property` callback shorthand
* _.some(users, 'active');
* // => true
