+# Two Ways To Find An Item In A List
+
+The `List` module has the typical `find` function that you'd expect any
+enumerable type to include. It has a very similar `find_opt` function as
+well. The difference is in the return types.
+
+When using `List.find` you'll have to deal with the possibility of a
+`Not_found` exception.
+
+```reasonml
+switch (List.find(item => item.id == id, my_list)) {
+| exception Not_found => print_endline("Not found!")
+| item => print_endline("Found it: " ++ item.name)
+}
+```
+
+The `List.find_opt` function has a more familiar interface that doesn't
+require you to know the details of what exceptions could arise. All you want
+to know is if it was found or _not_. This is achieved by having an
+`option('a)` return type.
+
+```reasonml
+switch (List.find_opt(item => item.id == id, my_list)) {
+| None => print_endline("Not found!")
+| Some(item) => print_endline("Found it: " ++ item.name)
+}
+```
+
+See the [`List` module](https://reasonml.github.io/api/List.html) for more
+details.
