Chapter 7 — Interfaces
An interface is a set of method signatures. Any type that has all of those methods satisfies the interface — automatically, without declaring intent. This is called structural or implicit typing.
閱讀文章 →Chapter 8 — Pointers and Memory
A pointer holds the memory address of a value. The type of a pointer to T is T. The zero value of any pointer is nil.
閱讀文章 →Chapter 9 — Generics
Generics arrived in Go 1.18 March 2022. They let you write functions and types that work on a parametric set of types, with compiletime type checking.

閱讀文章 →Chapter 12 — Modules and Dependencies
A module is a unit of versioning and distribution: a tree of Go packages identified by a module path, with explicit dependencies and a recorded build list. Modules replaced the older GOPATH workflow in Go 1.11+ and have
閱讀文章 →Chapter 13 — Practical Go
A grab bag of the topics you need most often in real services: HTTP, JSON, logging, configuration, structured project layout, and a few productionready patterns.
閱讀文章 →Chapter 1 — Arrays and Slices
Array NT — fixed length, length is part of the type, value semantics. Rarely used directly. Slice T — {ptr, len, cap} view into a backing array. Reference semantics for the underlying data. Used everywhere.
閱讀文章 →Chapter 2 — Stack
A stack is a LIFO lastin, firstout container with two main operations:
閱讀文章 →Chapter 3 — Queue Ring Buffer
A queue is a FIFO firstin, firstout container. The two main operations are:
閱讀文章 →Chapter 4 — Sorting
Sorting is the canonical algorithms topic. Knowing several sorts and their tradeoffs is part of any working programmer's vocabulary. This chapter implements five classic algorithms in Go and explains when to use each.
閱讀文章 →Chapter 5 — Hash Tables
A hash table maps keys to values with expected O1 lookup, insert, and delete. The trick: a hash function turns a key into an integer, which is reduced modulo the bucket count into an index, and an entry is stored at that
閱讀文章 →Chapter 6 — Binary Heap Priority Queue
A binary heap is an arraybased complete binary tree that satisfies the heap property:
