Rearranging Code: ->
| Difficulty: | Elementary |
| Topics: |
The -> macro threads an expression x through a variable number of forms.
First, x is inserted as the second item in the first form,
making a list of it if it is not a list already.
Then the first form is inserted as the second item in the second form,
making a list of that form if necessary.
This process continues for all the forms.
Using -> can sometimes make your code more readable.
 | (= (__ (sort (rest (reverse [2 5 4 1 3 6])))) (-> [2 5 4 1 3 6] reverse rest sort __) 5) |
