  1. Not sure I agree with a for loop over reduce.

    First I don’t think the list for things you have to keep in mind is correct. Why are you thinking about the previous value? If you’re doing that then you’re thinking about things being combined in a linear fashion which isn’t great. You should be thinking with pure functions when using functional methods.

    Also with the order – you already have the lengths and the limits. It’s the length of the array. It’s baked in. You get that for free. So the only thing with order is declaring the initial state. That’s also easy, just declare the variable first like you would with a for loop and pass it in if that’s the issue. But there is also a bonus with reduce – it takes a function. That means you can move that function out and just use a name. `ids.reduce(addItemToObject, {})`.

    The issue with a for loop is it can do anything. With reduce you are already hinting at what you want to do (i.e. reduce an array). The other factor that comes in is that with reduce you are expected to use a pure function (if you’re not then that’s a whole other issue). That takes a lot of context out of the equation, whereas a for loop can be using context from anywhere. So the only thing that is weird about it is the order.
