Because the value may change. If 'currentUrl' was a constant (eg. `const currentUrl = window.location.href`) it would capture the href at the start of the application, even though it might change later on (history API, pushstate etc).

Why wouldn't you just reference `window.location.href` when needed, instead of wrapping it up in `currentUrl`?

Yeah that was my question. I was racking my head thinking of when this window.location.href wouldn't refer to what a program would want given how it almost acts like a global function in some ways (e.g. `window.location.href="http://example.com"` can be used to change the page). Maybe currentUrl is supposed to be a wrapper just incase window.location.href changes (which seems highly unlikely but again, I'm out of the loop with modern JS).
