How can you create a map (dictionary) in a chosen programming language?

In Go, a map is created using the built-in make function. The syntax is as follows:

m := make(map[KeyType]ValueType)

For example, to create a map from strings to integers:

m := make(map[string]int)
m["apple"] = 5
m["banana"] = 3

You can also create a map with a literal initialization:

m := map[string]int{"apple": 5, "banana": 3}

A map in Go is a hash table that allows for fast retrieval, addition, and deletion of elements by key.
