_.forEach(collection, [iteratee=_.identity])
Iterates over elements of collection and invokes iteratee for each element. The iteratee is invoked with three arguments: (value, index|key, collection). Iteratee functions may exit iteration early by explicitly returning false.
Note: As with other "Collections" methods, objects with a "length" property are iterated like arrays. To avoid this behavior use _.forIn or _.forOwn for object iteration.

Example
1 2 3 4 5 6 7 8 9 | _.forEach([1, 2], function(value) { console.log(value);});// => Logs `1` then `2`. _.forEach({ 'a': 1, 'b': 2 }, function(value, key) { console.log(key);});// => Logs 'a' then 'b' (iteration order is not guaranteed). |
