In Go, the map data structure is implemented as a hash table that provides quick access to values by keys. When adding a key-value pair, the key is hashed, and the hash determines the index in the bucket array where the value is stored.

Main points of implementation:

  • Uses open addressing with chaining to resolve collisions.
  • In case of collisions, elements are stored in linked lists within the buckets.
  • When the number of elements increases, a reorganization (rehash) is performed to maintain performance.

Example of using a map in Go:

m := make(map[string]int)
m["apple"] = 5
value, exists := m["apple"]
if exists {
    fmt.Println("Value for 'apple':", value)
}
