Understanding Loop Functions within Xano: A Discussion on For Each, For and While Loops

This meeting among the State Changers revolved around understanding different types of loops, specifically in Xano, addressing 'for' loops, 'while' loops, 'for each' loops, 'loop break' and 'loop continue'. The key highlights include:

1. 'For each' loops are simple, effective, and low-risk when iterating over elements or 'objects' (like, apples in a bag). Participants agreed that these loops were best for the majority of use cases, due to their usability. 2. 'While' loops were discussed as being useful when the stop point is unpredictable. For instance, when downloading pages of data, where the total pages are unknown, a 'while' loop would be used until a condition signifying 'no more pages' is reached. 3. Notably, a question arose around a scenario where the maximum iteration limit could potentially be calculated in advance. The conclusion was that such a case can be solved by either a controlled 'for' loop or a 'while' loop. A 'while' loop would be simpler to implement but less safe; a 'for' loop would need more setup ('ceremony') but offer greater safety. 4. A 'for' loop was considered somewhat of a rarity. An applicable scenario might be trying an action up to a specific number of times, breaking the loop upon successful execution. 5. 'Loop break' was defined as exiting the current execution context, and 'Loop Continue' as skipping the remaining code in the current iteration moving directly to the next one. The listeners expressed gaining valuable insights from the meeting, helping them understand when to use different types of loops, primarily in Xano.
