> So, would it really matter if you are hiring someone who doesn't remember the difference between .call and .apply off the top of their head?
A good developer might not remember the answer to half of these at any given time, but if they at least knew the answer at one point then that should be enough to give a decent answer to most of these questions. E.g. 'They are two ways of calling a method, one involves passing the parameter list as an array, the other involves passing the parameters as positional arguments.'
Similarly, I don't remember offhand exactly how to fix a FUOC, all the nuances of the javascript 'this' keyword, or all the rules for resolving CSS specificity, but I could still probably answer all of those questions well enough to pass an interview. Unless the interviewer is super OCD, just saying something like, "There is an angular setting that can prevent most cases of FUOC, and if that doesn't work then you can manually hide the element until the page loads" should be good enough.
