Rearranging Code: ->>
| Difficulty: | Elementary |
| Topics: |
The ->> macro threads an expression x
through a variable number of forms.
First, x is inserted as the last 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 last 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.
