concatMap :: Foldable t => (a -> [b]) -> t a -> [b]
relude Relude.Foldable.Reexport
Map a function over all the elements of a container and concatenate the resulting lists.

Examples

Basic usage: 
>>> concatMap (take 3) [[1..], [10..], [100..], [1000..]]
[1,2,3,10,11,12,100,101,102,1000,1001,1002]

>>> concatMap (take 3) (Just [1..])
[1,2,3]
chainedTo :: Monad m => (a -> m b) -> m a -> m b
relude Relude.Monad
For chaining monadic operations in forward applications using (&) Named version of =<<. 
>>> Just [ 1 :: Int ] & chainedTo (viaNonEmpty head)
Just 1

>>> Nothing & chainedTo (viaNonEmpty head)
Nothing
(=<<) :: Monad m => (a -> m b) -> m a -> m b
relude Relude.Monad.Reexport
Same as >>=, but with the arguments interchanged.
