Hey, did anyone else notice the typo in the function name? It's `Setcurrent URL ()` instead of `setCurrentUrl()`. No wonder this code is giving us headaches!

I think the correct function name should be `setCurrentUrl()`. That would fix the problem.

Oh, I see what you mean. That typo could definitely cause some issues.

I'm just gonna close my eyes and point to an answer. Hey, what do you know? I landed on option C. Global scope, but still throws an error. Must be a bug in the code or something.

Maybe there's a typo or something causing the error. It's always tricky with scope in JavaScript.

Yeah, it's weird that it's a global variable but still throws an error. Must be a mistake in the code.

I think you're right, it seems like the url variable is global but there's an error on line 02.

Woah, hold up! What if the `setCurrentUrl()` function is actually setting the `url` variable to `window.location.href`, which could be different from the global `url` variable? In that case, option D might be the correct answer.

User 3: I agree, the function could be changing the url variable locally.

User 2: Yeah, that could be a possibility. It's important to consider the function's behavior.

User 1: I think option D might be correct if the function is setting the url variable.

I'm going with option B. The `url` variable is global, so `console.log('The current URL is: ' + url)` should work just fine.

But doesn't the function setCurrentUrl() define the url variable locally?

Hmm, this looks like a classic scope issue. I'm guessing the variable `url` is declared outside the `setCurrentUrl()` function, so it should have global scope. Let's see what the rest of the candidates think.
