How can I apply 'or' in Clojure?
clojure
Solution
You can use `some` with `identity` to do this:
(some identity [nil nil nil 1 nil 1])
=> 1
`some` returns the first truthy value from applying a function to a sequence, so this works because `1` is a truthy value.
Problem
I have a sequence of values. I want to know if any of them evaluates true. ``` (def input [nil nil nil 1 nil 1]) ``` I want to do something like this: ``` (apply or input) ``` But I can't because `or` is a macro not a function. Similarly this won't work ``` (reduce or input) ``` I've written my own ``` (def orfn #(if %1 %1 %2)) ``` And now this works ``` (reduce orfn input) ``` As does this slightly different approach, although it only tests for `nil`. ``` (not (every? nil? input)) ``` What's the 'right' way to `apply or` or equivalent?
