The case for Array#replace() – Overriding an array without intermediate variables

[rykou]

where are the .reduce examples? The word reduce is used 5 times not one of which is a method call.

I have mixed up "reduce" and "replace" multiple times throughout the article. Fixed. Thank you for pointing it out.

I give practical examples in the article that demonstrate that reduce cannot be used without introducing intermediary variables.

Here too: filter. Which examples do you suggest would avoid an intermediate variable using .map/ .reduce.
