what is the function/purpose of capture parameter in the addEventListener utils class?

[Knards]

Is there some trick to this import? I wrote out the functions in a file called utils, but when I import them way you did, and through reading in MDN Web Docs, all I get in the console is "Require is not defined". The 2 files are in the same directory. My last iteration is import { properCase } from './utils.js';
