arrayChunk

arrayChunk(array array, [integer chunkSize]) → array<array> chunks

This function is available from LeekScript 4 onward. Splits the list array into sublists of at most chunkSize elements and returns the list of these sublists. The last sublist may contain fewer than chunkSize elements.

Parameters

• array: The list to split.
• chunkSize: The maximum size of the sublists.

Return

• chunks: The resulting sublists.

Example

var numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
var sublists = arrayChunk(numbers, 4)
debug(sublists) // [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10] ]

const numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
const sublists = []
for (let i = 0; i < numbers.length; i += 4) {
	sublists.push(numbers.slice(i, i + 4))
}
Debug.log(sublists) // [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10] ]

import itertools
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
sublists = [list(c) for c in itertools.batched(numbers, 4)]
Debug.log(sublists)  # [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10] ]
