An open-source book (in Chinese) that explains the implementation principles and evolution of the Go language by studying its source code, covering the runtime, toolchain, concurrency, memory, and standard library. It is based on Go 1.26 and available online at golang.design/under-the-hood.

Use cases

• understand how the Go runtime implements goroutines and the scheduler
• learn how Go's garbage collector and memory allocator work internally
• study how the Go compiler and toolchain are implemented
• deepen understanding of Go language design decisions and trade-offs
• prepare for deep Go source code reading
• learn Go internals before a systems interview

When to choose

• you want a deep, source-code-level explanation of Go's implementation
• you read Chinese and want a comprehensive Go internals book
• you want to understand runtime, compiler, and concurrency internals rather than just syntax

When to avoid

• you need a beginner tutorial for writing Go applications
• you need English-only material
• you need a quick reference rather than an in-depth book
