On proactively naming elements within Cypress

Anytime you use .within() in a Cypress test, you have the option to name the element variable that you pass into the function body. Here's an example where the element scope is named:

cy.get('#el').within(('optionallyNamedElement') => {
  cy.log('foo');
});
Copy after login

but here's another perfectly functional example where it isn't:

cy.get('#el').within(() => {
  cy.log('foo');
});
Copy after login

If the named element term isn't used in the function body, should we assign it a name when we write this test code? I think we should.

It's ok if someone comes along later and changes this name, but I think it's a courtesy to future programmers to give them a semantic name here for future use. This name might use a consistent style across the test codebase, or just provide a way for a future programmer to avoid getting stuck in future by having to pause to come up with a name. Remember, that future programmer might be you!

I also think that proactively providing a name here makes code more clear, approachable, and debuggable. By naming the element, when a bug arises, you at least have a clue of what element you thought you were scoped within.

When I use .within() these days, I always try to remember to name the scope that I'm entering, even when that variable never gets used in the function body.
