How do you split an array into array pairs in JavaScript?

Question

I want to split an array into pairs of arrays.

var arr = [2, 3, 4, 5, 6, 4, 3, 5, 5]

would be

var newarr = [
    [2, 3],
           


        

Answer 1

const items = [1, 2, 3, 4, 5];

const createBucket = (bucketItems, bucketSize) => buckets => {
  return bucketItems.length === 0 ? buckets : [...buckets, bucketItems.splice(0, bucketSize)];
};

const bucketWithItems = items.reduce(createBucket([...items], 4), []);
