accumulate

core-api



    function
    boot.janet on line 1011, column 1

    (accumulate f init ind)

    Similar to `reduce`, but accumulates intermediate values into an 
    array. The last element in the array is what would be the return 
    value from `reduce`. The `init` value is not added to the array 
    (the return value will have the same number of elements as `ind`). 
    Returns a new array.

(accumulate string "ha" ["ha" "ha" "ha" "ha"]) # => @["haha" "hahaha" "hahahaha" "hahahahaha"]
