Find meaningful names for computation units.
Use for comprehensions or map to combine computations together.
Let's say you have something like this:
if (userAuthorized.nonEmtpy) {
makeRequest().map {
case Success(respone) =>
someProcessing(..)
if (resendToUser) {
...
By default:
Use val, not var, wherever possible. This allows you to take seamless advantage of a number of functional utilities, including work distribution.
Use recursion and comprehensionss, not loops.

In wordpress admin we use pre defined shortcodes by writing the shortcode name inside square brackets and optionally adding attributes to it separating by space.
However, x in the generator expression is not just variable, but can be any pattern. In cases of pattern mismatch the generated element is skipped over, and processing of the list continues with the next element, thus acting like a filter:
[x | Just x <- [Just 1, Nothing, Just 3]] -- [1, 3]
...
With Parallel List Comprehensions language extension,
[(x,y) | x <- xs | y <- ys]
is equivalent to
zip xs ys
Example:
[(x,y) | x <- [1,2,3] | y <- [10,20]]
-- [(1,10),(2,20)]
