It Chunk

docs/data/it-chunk.md

1.53.0592 B
Original Source

Returns a sequence of elements split into groups of length size. The last chunk may be smaller than size.

Examples:

go
seq := func(yield func(int) bool) {
    _ = yield(1)
    _ = yield(2)
    _ = yield(3)
    _ = yield(4)
    _ = yield(5)
}
chunks := it.Chunk(seq, 2)
var result [][]int
for chunk := range chunks {
    result = append(result, chunk)
}
// result contains [1, 2], [3, 4], [5]

Note

it.ChunkString and it.Chunk functions behave inconsistently for empty input: it.ChunkString("", n) returns [""] instead of [].
