worth pulling this off of url
on line 79, in case there's a getter, so as to unconditionally trigger it?

That seems wasteful, I'm not sure I understand what would be the upside of doing so

Example benefits:
- a getter that throws will do so at the top of the method, before expensive stuff happens
- algorithm changes won't be as observable - it would otherwise be part of the API of this to only do a Get of "pathname" in this branch, and to only do one total, so refactors could become unintentional breaking changes
- it becomes much clearer what properties are accessed since they're all accessed once, statically, at the top of the method

If we really care about this, I think we should rather adapt the regex to take the href
rather than the pathname
.

It's still the first operation after the destructuring in that function.

You mean if we start needing pathname
for other protocols? But a case could be made for the other properties of URL, what if we end up needing search
or origin
, should we get them as well just in case?

yep (to be clear, i don't mean get them now just in case, i mean as soon as they're used once in the function, get them unconditionally at the top)
What is the goal here? |
Reduce unnecessary URL initializations. |
* @param {URL} url URL to the module | ||
* @param {ESModuleContext} context used to decorate error messages | ||
* @returns {{ responseURL: string, source: string | BufferView }} | ||
*/ | ||
function getSourceSync(url, context) { |

nit: I think that is not necessary because the code doc already identifies it as type URL
, and I think (aside from mistakenly constructing a new instance), the difference likely would not matter because it's castable to a string.
That said, I do sometimes do similar things, like fooRgx
, so I'm not opposed to it (just pointing out that info is already available).

Another thing to consider is that the async implementation also uses url
and not urlInstance
as a name, and since this PR goal is to align both implementation, that seems to be another reason not to take that suggestion in that PR

I don't really care, you can feel free to disregard. I suggested it because I think I saw we called this urlInstance
somewhere else in the file, so we might want to standardize at some point.
