Everything is looking really good! The only things that are missing are prototypes and the readme questions. Try your best with prototypes, and definitely use the guided project and solution code for JS 3 if you get stuck!

Excellent work creating objects!

Make sure to add the roar method!

Awesome that you are using arrow syntax!

This challenge is asking you to use .map()
| console.log(largerPopulation); | ||
|
|
||
| const smallerPopulation = zooAnimals.filter((animal,i) => zooAnimals[i].population < 5); | ||
| const smallerNames = smallerPopulation.map( (animal,i) => (`${smallerPopulation[i].animal_name}, Population: ${smallerPopulation[i].population}`)); |

It's awesome that you used .map() here for better formatting! Know that you don't need to create a separate variable here, as you can just chain the .map() method on after your .filter() method.
| // Explain in your own words why `nestedfunction()` can access the variable `internal`. | ||
|
|
||
| // Explanation: | ||
| console.log(`Explanation: nestedFunction() is able to access the variable internal, even though it is outside of the function scope. This is because of the concept in javascript known as a closure. Javascript allows for this behavior in order to allow functions to behave correctly. Technically, a function cannot access variables outside of it's scope. But because of the closure, a nested function can access variables in functions outside of it, and even in the global context.\n`); |

This is an excellent answer!

Awesome that you added an additional property here
…as unable to commit the changes to git.
…oAnimals array instead of creating another array and running an array method on each variable array.

I just commited the changes that you suggested and the readme file has been pushed correctly. Please re-review. Thanks! |

Looking good! It doesn't look like you're using the second parameter in your callback function, so you could remove it
