+### Clean JSON object
+
+Use `Object.keys()` method to loop over given json object and deleting keys that are not `include`d in given array.
+also if you give it a special key(`childIndicator`) it will search deeply inside it to apply function to inner objects too.
+
+```js
+const cleanObj = (obj, keysToKeep = [], childIndicator) => {
+  Object.keys(obj).forEach(key => {
+    if (key === childIndicator) {
+      cleanObj(obj[key], keysToKeep, childIndicator);
+    } else if (!keysToKeep.includes(key)) {
