Nice, https://github.com/tc39/proposal-slice-notation/issues/19#issuecomment-421453934 is really awesome. I hope this idea doesn't get abandoned
I feel you can swap things easily already; ```js let x = 1, y = 2; [x, y] = [y, x]; ``` Chunks could be written ```js // take chunks of 4 from arr // with slice+range operator proposal const chunks = [0:Math.ceil(arr.length/4)].map(i => arr[4*i:4*(i+1)]) // vs const chunks = Array.from({length: Math.ceil(arr.length/4)}, (_,i) => arr.slice(4*i, 4*(i+1))) ``` On Tue, May 28, 2019 at 12:05 PM Joseph Rocca <rocca.jos...@gmail.com> wrote: > Apologies if this has already been suggested and discussed somewhere, but > I couldn't find anything.
