Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Javascript doesn't enforce the use of caps for const like other languages may, ruby for example. However, there are a few JS style guides out there which define linting rules that are well defined. Google and Airbnb (https://github.com/airbnb/javascript#naming-conventions) are two examples of such guides.
Shouldn't the const naming convention be like POP_ELEMENT AND GET_LENGTH with capital letters and an underscore between words or is it different for javascript?
