for_each()

Iterates over elements of collection and invokes iteratee for each element. The iteratee is invoked with three arguments: (value, index|key, collection). Each invocation of iteratee is called for its side-effects upon the collection. Collection may be either an object or an array. Iteration is stopped if predicate returns Falsey value. The predicate is bound to thisArg and invoked with three arguments: (value, index|key, collection).

Implementation

Args: collection: The collection to iterate over. func: The function invoked per iteration. Returns: The collection.

Example

for_each([1, 2, 3], lambda x: print(x))

Expected output: 1 2 3
