func chunkBy(items []string, chunkSize int) (chunks [][]string) { | |
for chunkSize < len(items) { | |
items, chunks = items[chunkSize:], append(chunks, items[0:chunkSize:chunkSize]) | |

You can allocate memory use make() like
var chunks = make([][]string, 0, len(items) / chunkSize + 1)
// or
// if use this variant, need to be add index into cycle and access via index
var chunks = make([][]string, len(items) / chunkSize + 1)
And you can do like that
this
items[0:chunkSize:chunkSize]
to
items[:chunkSize:chunkSize]
Nice! Thanks to your code + @kamnev8823 suggestion, here's my final code I shared on StackOverflow (it includes generics support): https://stackoverflow.com/a/72408490/3971297
