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

	return append(chunks, items)
}

thank you

Thank you

thanks

Nice!

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
