Returns array of arrays, with internal arrays of size (columns) supplied.

|
||||
```js
|
||||
const covertArrayTo2DMatrix = (items, columns) => {
|
||||
let data = []
|
||||
if (items?.length && columns) {
|
||||
const rows = columns ? Math.ceil((items?.length ?? 0) / columns) : 0
|
||||
for (let i = 0; i < rows; i++) {
|
||||
let row = []
|
||||
for (let j = 0; j < columns; j++) {
|
||||
const element = items[i + j + i * (columns - 1)]
|
||||
if (element) {
|
||||
row.push(element)
|
||||
}
|
||||
}
|
||||

||||
|
||||
```js
|
||||
covertArrayTo2DMatrix([1, 2, 3, 4, 5, 6], 3); // [[1, 2, 3], [4, 5, 6]]
|
||||
covertArrayTo2DMatrix([1, 2, 3, 4, 5, 6], 2); // [[1, 2], [3, 4], [5, 6]]
|
||||
covertArrayTo2DMatrix([1, 2, 3, 4, 5], 3); // [[1, 2, 3], [4, 5]]
