+# `last()`
+
+The last method returns the last element in the collection that passes a given truth test:
+
+```js
+const collection = collect([1, 2, 3]);
+
+const last = collection.last(item => item > 1);
+
+// 3
+```
+
+You may also call the last method with no arguments to get the last element in the collection. If the collection is empty, `null` is returned:
+
+```js
+collect([1, 2, 3, 4]).last();
+
+// 4
+```
