[null,null,["Last updated 2023-10-06 UTC."],[],["`iterate()` applies a user-defined function to each collection element. This function receives the current element and the prior iteration's result as arguments. The process starts with an optional initial state (`first`). The final output is the value produced by the user-defined function's last execution. It's used on a `Collection` with the `algorithm` being a function and `first` as optional. It returns a `ComputedObject`.\n"]]
