While () and For Each () in ()

[Chikorita-Lover]

Hello, just today I noticed that there are two custom blocks in the control category in the TurboWarp editor: While (), and For Each () in (). I have a few questions regarding these:

• How come these aren't in any TurboWarp docs?
• What does For Each () in () do?
• Can these be exported and used on the Scratch website?

• Never bothered, I guess. Not really a clear spot for it. Some of these old decisions predate the GitHub wiki entirely.
• It's a loop similar to "set i to 1, repeat n times {do something, change i by 1}"
• Yes

Thanks! I just found the page "Hidden Blocks" on the Scratch Wiki and have been reading up on it, these seem pretty useful and would love to mess around with them.
