+### renameKeys
+
+Replaces the names of multiple object keys with the values provided.
+
+Use `Object.keys()` in combination with `Array.reduce()` and the spread operator (`...`) to get the object's keys and rename them according to `keysMap`.
+
+```js
+const renameKeys = (keysMap, obj) => Object
+    .keys(obj)
+    .reduce((acc, key) => ({
+        ...acc,
+        ...{ [keysMap[key] || key]: obj[key] }
+    }), {});
+```
+
+```js
+const obj = { name: 'Bobo', job: 'Front-End Master', shoeSize: 100 };
+renameKeys({ name: 'firstName', job: 'passion' }, obj); // { firstName: 'Bobo', passion: 'Front-End Master', shoeSize: 100 }
+```
