This Go code demonstrates how to convert a slice into a map using generics. It includes a generic function `SliceToMap` that takes a slice, and a key function to generate keys for the resulting map. The code provides a simple example of converting a string slice to a map with integer keys.

package main

import "fmt"

func SliceToMap[I ~[]V, K comparable, V any](arr I, keyFunc func(i int) K) map[K]V {
	m := make(map[K]V)
	for i := range arr {
		m[keyFunc(i)] = arr[i]
	}

	return m
}

func main() {
	s := []string{
		"Hello", "Bye", "Bye",
	}

	m := SliceToMap(s, func(i int) int {
		return i
	})

	fmt.Println(m)
}
