Challenge: Define let/const variables
- [Narrator] Okay, so now let's put all this new knowledge together in a final challenge. Since ES6 and beyond uses mostly const and let, in this challenge, we'll only use those two. So here's the new challenge, first declare an immutable variable in the global scope listing a few warriors and their attributes. Then in a function, if the attribute of a warrior meets a certain requirement, list that warrior into the console. Also, constantly log what variables is accessible where so you demonstrate to yourself you understand their scope. Feel free to leverage some of the examples with it today in this course and good luck.
