#JavaScript is becoming more and more functional!
Iterator helpers, a stage3 TC39 proposal that brings lazy sequences to JS, is already implemented by V8 (Chrome & #Nodejs 22+)
Below an example with square integers showing how it helps reduce computations.
IMHO this is pure gold!

For once I will say something nice about Safari... and even Bun...
Thanks to their JavaScript engine, Apple JavaScriptCore, they both benefit from Tail Call Optimization (TCO) 🙌
