In module 5, we have the line

import { v4 as uuidv4 } from 'https://jspm.dev/uuid';

"uuidv4" is just so it's easy for the programmer to remember and not accidentally use the default v4 variable. Is there a name for when you give a new name to a variable? For example, is it called a renamed variable, a handy variable, or something like that?

Yep, mdn docs call that an "alias":

import - JavaScript | MDN

The static import declaration is used to import read-only live bindings which are exported by another module. The imported bindings are called live bindings because they are updated by the module that exported the binding, but cannot be modified by the importing module.
