ForEach

Name	-	Description	Default	Type
<input>		Sequence/table whose elements or key-value pairs need to be processed.		[Any]{Any}
<output>		The output from processing the sequence/table elements or key-value pairs.		[Any]{Any}
Apply		The processing logic (in the form of a shard or sequence of shards) to apply to the input sequence/table.	None	Shard[Shard]

Processes every element or key-value pair of a sequence/table with a given shard or sequence of shards.

Examples
