ReasonML Quick Start Guide

take

The take function accepts a list and a length and returns a subset of the list starting from the head of the list with length equal to the requested length. Since the requested length of the subset may exceed the original list's length, the result is wrapped in an option. Its type is as follows:

(Belt.List.t('a), int) => option(Belt.List.t('a))

We can take the first two items from our shuffled list, like so:

let list = Belt.List.(makeBy(10, i => i)->shuffle->take(2));
