In F#, what is the difference between functions "Seq.collect" and "Seq.map"? They seem equivalent from the description on MSDN.
If you know LINQ, the following comparison may be useful:
F#: Seq.map
, LINQ: Select
F#: Seq.collect
, LINQ: SelectMany
Seq.collect
will first map each sequence element to a new sequence and flatten this sequences into a single one.
Seq.map
will just map each element to a new element .
