How to Use the slices and maps Packages with Iterators

Use slices for ordered collections and maps for key-value pairs to iterate over data without manual index management. Import both packages and apply their functions directly to your data structures.

import (
	"maps"
	"slices"
)

// Iterate over sorted map keys
for _, k := range slices.Sorted(maps.Keys(paxHdrs)) {
	fmt.Println(k, paxHdrs[k])
}

// Iterate over sorted slice values
for _, v := range slices.Sorted(mySlice) {
	fmt.Println(v)
}

The slices package helps you sort and manage lists of items, while the maps package handles collections of key-value pairs. Using them together lets you process data in a predictable order without writing complex loops. Think of slices as a tool to organize a deck of cards and maps as a dictionary where you look up words by their first letter.
