Hello there. I have seen an implementation of nodejs’ require function - but it needed to use a variable-function ($require(string $name)) instead, because ‚require()‘ is given. My questions are: - Why is require still also available as a function? - Why can’t re re-define something like that? Kind regards, and thanks! ^^
