+### invertKeyValues
+
+Inverts the key-value pairs of an object, without mutating it.
+
+Use `Object.keys()` and `Array.reduce()` to invert the key-value pairs of an object.
+
+```js
+const invertKeyValues = obj => Object.keys(obj).reduce((acc,key) => { acc[obj[key]] = key; return acc;},{});
+```
+
+```js
+invertKeyValues({name:'John', age: 20}) // { 20: 'age', John: 'name' }
+```
