* Checks if `predicate` returns truthy for **any** element of `collection`.
|
||
|
|
* Iteration is stopped once `predicate` returns truthy. The predicate is
|
||
|
|
* invoked with three arguments: (value, index|key, collection).

|
||
|
|
* @param {Array|Object} collection The collection to iterate over.
|
||
|
|
* @param {Function} [predicate=_.identity] The function invoked per iteration.
|
||
|
|
* @param- {Object} [guard] Enables use as an iteratee for methods like `_.map`.
|
||
|
|
* @returns {boolean} Returns `true` if any element passes the predicate check,
|
||
|
|
* else `false`.
|

* @example
|
||
|
|
*
|
||
|
|
* _.some([null, 0, 'yes', false], Boolean);
