+# Accessing Arguments To A Function
+
+The `arguements` object is available within any JavaScript function. It is
+an array-like object with all of the arguments to the function. Even if not
+all of the arguments are referenced in the function signature, they can
+still be accessed via the `arguments` object.
+
+```javascript
+function argTest(one) {
+  console.log(one);
+  console.log(arguments);
+  console.log(arguments[1]);
+}
+
+argTest(1);
+// 1
+// [1]
+// undefined
+
+argTest(1, 'two', true);
+// 1
+// [1,'two',true]
+// 'two'
+```
+
+See the [Arguments object
+docs](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/arguments)
+on MDN for more details.
