+## Stopping
+
+Normally, you don't want to stop the traversal. For example, here we gather all the traversed paths. Remember the format is universal, you can use it in [`object-path`](https://www.npmjs.com/package/object-path) for example.
+
+```js
+const traverse = require("ast-monkey-traverse");
+const input = { a: "1", b: { c: "2" } };
+const gathered = [];
+traverse(input, (key1, val1, innerObj) => {
+  const current = val1 !== undefined ? val1 : key1;
+  gathered.push(innerObj.path);
+  return current;
+});
+console.log(gathered);
+// => ["a", "b", "b.c"]
+```
+
+Now let's make the monkey to stop at the path "b":
+
+```js
+const traverse = require("ast-monkey-traverse");
+const input = { a: "1", b: { c: "2" } };
+const gathered = [];
+traverse(input, (key1, val1, innerObj, stop) => {
+  const current = val1 !== undefined ? val1 : key1;
+  gathered.push(innerObj.path);
+  if (innerObj.path === "b") {
+    stop.now = true; // <---------------- !!!!!!!!!!
+  }
+  return current;
+});
+console.log(gathered);
+// => ["a", "b"]
+```
+
+Notice how there were no more gathered paths after "b".
