Variable: chunk()

const chunk: {<Size>(size): <Value>(iterable) => Iterable<Value[]>; <Size, Value>(size, iterable): Iterable<Value[]>; }

Defined in: splices.d.ts:888

Returns an iterable equivalent to iterable except its values are grouped into arrays that each contain size values.

The last array in the returned iterable will contain fewer than size values (but at least one) if the number of values in iterable is not divisible by size.

<Size>(size): <Value>(iterable) => Iterable<Value[]>

Type Parameters

PositiveInteger<Size>

Returns

<Value>(iterable): Iterable<Value[]>

Type Parameters

Example

console.log(
pipe(
[1, 2, 3, 4, 5, 6, 7, 8, 9],
chunk(3),
reduce(toArray()),
),
)
//=> [ [ 1, 2, 3 ], [ 4, 5, 6 ], [ 7, 8, 9 ] ]

console.log(
pipe(
[`S`, `L`, `O`, `T`, `H`],
chunk(2),
reduce(toArray()),
),
)
//=> [ [ 'S', 'L' ], [ 'O', 'T' ], [ 'H' ] ]
