Convert a Go slice to a map by iterating through the slice and assigning key-value pairs to a new map instance.
Convert a slice of key-value pairs to a map by iterating through the slice and assigning each pair to the map. Use a for loop with range to access elements and set them in the map.
slice := []struct{ K, V string }{{"a", "1"}, {"b", "2"}}
result := make(map[string]string)
for _, item := range slice {
result[item.K] = item.V
}
Converting a slice to a map in Go turns a list of items into a lookup table where you can find values by their keys instantly. Think of it like organizing a list of names and phone numbers into a phonebook so you can look up a number by name without scanning the whole list. You use this when you need fast access to data based on a specific identifier.
