Well, if the developer is creating custom components, or simply manipulating data, then they need to know some good algorithms (at least know they exist and what to look for). Like when creating a table that needs to sort the rows. If you don't know how to do this, then you could have a really bad 0(N2) algorithm that just kills the browser with even a small list of items. Or, if you need write an algorithm to pack a bunch of rectangles on a screen (like a day calendar) so they don't overlap.

Yes, there are computer science topics that apply to the front end. If you are writing Javascript (not just marking up stuff and applying CSS), then you want to know how this works. This isn't the 90's simple form submission javascript. It's a completely different world in the browser now.
