Is there any difference in terms of what happens in the backend Or are they identical in the sense that map just hides away the for loop

Khuyen Tran · Answer

I believe map just hides away the for loop But maybe you can answer this better than me < Zanie> < Anna Geller>

Zanie · Answer

`map` is a bit more performant than a for loop as we gather all upstream dependencies concurently

Zanie · Answer

If you re calling `map` without any upstream tasks as inputs it s probably going to be the same as a for loop I believe in the future we ll collapse mapped tasks in the UI and such to make the graph clearer
