For that, I'd rather see an `interleave` that just rotates through all its arguments. It'd be basically sugar for `.zip().flat()`, but an implementation could optimize the heck out of it. (In particular, they could iterate through them one-by-one and only allocate once, not in the hot loop, so it'd be fast.)
I at one point had it in my list of wishlist proposals, but it somehow disappeared. I've since recreated it: https://github.com/isiahmeadows/es-stdlib-proposals/blob/master/proposals/array/interleave.md ----- Isiah Meadows [email protected] www.isiahmeadows.com On Thu, Aug 15, 2019 at 1:12 PM Andrea Giammarchi <[email protected]> wrote: > > That;s not useful for template literals tags though > > _.zip(['a', 'b', 'c'], [1, 2]); > [["a", 1], ["b", 2], ["c", undefined]] > > it basically does nothing I've proposed ... any other name suggestion? > > On Thu, Aug 15, 2019 at 3:40 PM Michał Wadas <[email protected]> wrote: >> >> https://lodash.com/docs/#zip >> https://docs.python.org/3/library/functions.html#zip >> >> On Thu, 15 Aug 2019, 15:34 Andrea Giammarchi, <[email protected]> >> wrote: >>> >>> the suggested name is just ... suggested, I don't have strong opinion on >>> it, it just `join` values through other values >>> what's `Array.zip` ?
