How to Split a List into N Equal Parts in Ruby (and Rails)

Earlier this week, I wanted to render a list of items on a website in a grid of 3 columns per row. Typically, I'd resort to Tailwind's Grid to accomplish this, but I wanted to do it programmatically in Ruby. While trying to hack a solution with loops and conditions, I came across the each_slice method in Ruby.The each_slice method breaks the list into multiple, smaller lists of a given size. Since it returns self enumerator, you'd call to_a on it to get the chunked list.
