Could you explain what the term 'bucket' means in the context of the Map data structure?

In the context of the Map data structure in Go (Golang), the term "bucket" refers to an internal element of the hash table used to store multiple key-value pairs that have the same hash index.

When a collision occurs (different keys have the same hash), these pairs are grouped into one bucket. Each bucket contains several slots for storing elements and also serves to organize data so that search, insert, and delete operations remain efficient.

You can roughly think of a bucket as a "basket" where all elements with the same hash index are placed. In Go, the map implementation uses an array of such buckets and adds new ones as needed to handle growth and collisions.

Thus, a bucket is a structural element that ensures efficient storage and retrieval in the hash table map.
