select first item of a collection that satisfies given predicate in clojure

Question

Is there a function in clojure that (given a predicate and a collection), selects the first item that satisfies the given predicate and stop the iteration? for example: ``` (select-first #(> % 10) (range)) => 11 ``` If not, maybe someone could hint me about an idiomatic implementation

Accepted Answer

There are multiple possibilities. `some` `some` returns the first non-nil value its predicate returns. ``` (some #(when (> % 10) %) (range)) ;; => 11 ``` `filter` + `first` `filter` retains those elements that match a predicate, `first` retrieves the first of them. ``` (first (filter #(> % 10) (range))) ;; => 11 ``` `remove` + `first` If you want to find the first element that does not match your predicate, `remove` is your friend: ``` (first (remove #(<= % 10) (range))) ;; => 11 ``` Or with `some`: ``` (some #(when-not (<= % 10) %) (range)) ;; => 11 ``` So, that's it, I guess.
