In BQN ⎉ is Rank and ∘ is Atop. Dyalog's Atop (⍤) and Over (⍥) were added in version 18.0.

For writing

The tables below give approximate implementations of Dyalog primitives for the ones that aren't the same. First- and last-axis pairs are also mostly omitted. BQN just has the first-axis form, and you can get the last-axis form with ⎉1.

The form F⍣G (Power with a function right operand; Power limit) must be implemented with recursion instead of primitives because it performs unbounded iteration. The modifier _while_ ← {𝔽⍟𝔾∘𝔽_𝕣_𝔾∘𝔽⍟𝔾𝕩} provides similar functionality without risk of stack overflow. It's discussed here and called as Fn _while_ Cond arg.
