Go's standard library provides several built-in data structures that are readily available for use in various applications.

• Arrays: Fixed-size collections of elements of the same type. The size of an array is part of its type.
• Slices: Dynamically-sized, flexible view into the elements of an array. They are more commonly used than arrays.
• Maps: Collection of key-value pairs, providing average O(1) time complexity for lookups, inserts, and deletes.
• Strings: Immutable sequences of bytes, often used to store text. They have a rich set of methods for manipulation.
• Channels: Typed conduits through which you can send and receive values with the channel operator, <-. They are used for communication between goroutines.
• container/list: Provides a doubly linked list.
• container/heap: Provides heap operations for implementing priority queues.
• container/ring: Provides circular list (ring buffer) functionality.
• Sets: While Go doesn't have a built-in set type, you can use maps to implement sets. golang-set.
• sync.Map: A map with safe concurrent access.
• math/bits: Provides bit manipulation functions, although not a full bit set data structure.
