- Take advantage of short functions. For example, something like
(some-function(def a val)a) can be (|(some-function $ $)val)
- Recursive functions are often shorter than mutable variables.
(defn f[a]...)(f a) => ((fn f[a]...)a)
- Use
pp instead of print for numbers and quotes
- Often you can use a symbol or quote instead of a string, e.g.
"Fizz" => 'Fizz or :Fizz. Using 'Fizz also means it will work with pp
case often saves over if- Read the docs. There are a lot of useful functions in there.
- Splice is useful, e.g.
sum => +;, or you can do string; to join a list, print;, etc.
- Remove
in unless you need the default argument. You can just do ([a b c]idx)
