+Found out last night that `Array.reduce` in Godot 4.4 does not work the way I would have expected coming from a functional programming background.
+
+I wanted to write a function which would fold over a list and return best suitable match based on some criteria or `null` if none of those results were appropriate. However, I found that when I used `reduce`, it would keep picking an inappropriate result (which happened to be at the front of the list).
+
+According to the documentation for [`reduce`](https://docs.godotengine.org/en/4.4/classes/class_array.html#class-array-method-reduce), this is because of how the `accum` parameter works:
+
+> The method takes two arguments: the current value of `accum` and the current array element. If `accum` is `null` (as by default), the iteration will start from the second element, with the first one used as initial value of `accum`.
+
+Which means that even though `reduce` has the same type signature as `foldl`, if `accum` happens to be null it turns into what would be a `foldl1` in Haskell. The solution was to use a `for` loop instead.
+
+A chatter `Reaganomicon` mentioned that JavaScript, F#, and Python's `functools` also implement reduce in the same way.
+
+JavaScript does implement [`reduce`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reduce) in a similar way:
+
+> The value resulting from the previous call to `callbackFn`. On the first call, its value is `initialValue` if the latter is specified; otherwise its value is `array[0]`.
+
+But, if you call `reduce` with `null` or `undefined`, the function works correctly (at least in Firefox 136.0):
+
+> ```js
+> console.log([1].reduce((acc, v) => null, null))
+> console.log([1].reduce((acc, v) => null, undefined))
+> console.log([1].reduce((acc, v) => null))
+> ```
+> Prints:
+> ```
+> null
+> null
+> 1
+> ```
+
+This is probably because JavaScript functions can check how many arguments a user defined even if one of those arguments is undefined.
+
+F# also [does it correctly](https://fsharp.github.io/fsharp-core-docs/reference/fsharp-collections-arraymodule.html#reduce) as it has both `Array.fold folder state array` and `Array.reduce reduction array` (which have the same type signatures as `foldl` and `foldl1` respectively in Haskell)
+
+And it turns out that `functools` in Python 3 also implements [`reduce`](https://docs.python.org/3/library/functools.html#functools.reduce) correctly:
+
+> ```py
+> import functools
+>
+> print(functools.reduce(lambda x, y: None, [1], None))
+> 
+> print(functools.reduce(lambda x, y: None, [], 1))
+> ```
+> Prints:
+> ```
+> None
+> 1
+> ```

+# `reduce` returns first value in array when accumulator is `null`
+
+`Array.reduce` as of Godot 4.4 will use the first element in the array when the accumulator is either undefined or explicitly set to `null` by the user, contrary to how JavaScript, F#, and Python works. [^1]
+
+This means that you cannot write a function to pass to `reduce` that would fold over a list and return the best suitable match based on some criteria or `null` if none of those elements are appropriate. This is because it could keep picking an inappropriate result if one exists at the front of the list. [^1]
+
+If you are familiar with Haskell, another way of thinking about it is that `reduce` in GDScript silently turns into `foldl1` when `Nothing` is passed to `foldl` as the initial value for the accumulator. [^1]
+
+This behavior is documented in the documentation for [`reduce`](https://docs.godotengine.org/en/4.4/classes/class_array.html#class-array-method-reduce), this is because of how the `accum` parameter works: [^1]
+
+> The method takes two arguments: the current value of `accum` and the current array element. If `accum` is `null` (as by default), the iteration will start from the second element, with the first one used as initial value of `accum`.
