How to Use the slices and maps Packages (Generic Standard Library)

The slices and maps packages provide generic functions to manipulate slices and maps without writing boilerplate loops. Import them and call the specific function you need, such as slices.Sorted to get a sorted list of keys or maps.Copy to duplicate a map.

import (
	"maps"
	"slices"
)

// Get sorted keys from a map
keys := slices.Sorted(maps.Keys(myMap))

// Copy a map
newMap := maps.Clone(myMap)

// Check if a slice contains a value
found := slices.Contains(mySlice, targetValue)

These packages are like a Swiss Army knife for your data lists and dictionaries. Instead of writing repetitive code to sort, copy, or search through your data, you just call a simple function that does it for you. Think of it as having a built-in assistant that handles the tedious data chores so you can focus on your main logic.
