You get at:

- **Level 21 - Summit’s Gate**
- Programmaticon 5 book - _Skills: Full - Vector, Math, String, Function, Array, and Object APIs_

Some of the documentation needs updating / in this case replacing hero with this / and I didn’t try if everything works.  
From the topic [Use of Programmaticon V's array methods](https://discourse.codecombat.com/t/use-of-programmaticon-vs-array-methods/6745) :  
Nick: “we don’t document it, but Lodash functions are also available as well”  
I tried some of them successfully an some not.

Edit:  
Sorry for telling you things you perfectly know : you are one of the fist CodeCombat warriors. Respect! 🙂 -)
