How to map an array vertically into columns?

var array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18],
    chunk = 5,
    result = array.reduce((r, v, i) => {
        (r[i % chunk] = r[i % chunk] || []).push(v);
        return r;
    }, []);
    

result.forEach(a => console.log(...a));

const array = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 ]
const chunkSize = 5;

let result = [];
for (let i = 0; i < chunkSize; i++) {
    result[i] = [];
}

array.forEach((e,i) => {
    result[i % chunkSize].push(e);
});

console.log(result); 
/* 
Result : 
[ [ 1, 6, 11, 16 ],
  [ 2, 7, 12, 17 ],
  [ 3, 8, 13, 18 ],
  [ 4, 9, 14 ],
  [ 5, 10, 15 ] ]
