+# How to Use the ForEach Method
+
+---
+
+In JavaScript, the `.forEach()` method lets you execute the function you provide once for each element in a given array.
+
+```js
+const animals = ["Giraffe", "Orangutan", "Elephant"]
+
+animals.forEach((animal) => console.log(animal))
+
+// Giraffe
+// Orangutan
+// Elephant
+```
