In what scenarios have you used the Map data structure in your projects?

In Go, the data structure Map is often used for quick access to data by key. In projects, I have used Map in the following scenarios:

• Caching the results of computations or queries to speed up repeated access.
• Storing configuration parameters, where the key is the parameter name, and the value is its value.
• Counting the number of occurrences of elements (for example, words in a text).
• Associating identifiers with objects or structures for quick lookup.

Example of counting the number of words:

words := []string{"apple", "banana", "apple", "orange", "banana", "apple"}
count := make(map[string]int)
for _, word := range words {
    count[word]++
}
fmt.Println(count) // map[apple:3 banana:2 orange:1]
