The Ultimate Go Playbook: From High School Basics to Bare-Metal Scale

Learning Path

Phase	Weeks	Modules	Focus
🌱 Foundations	1-3	Foundations, Data Structures, Interfaces	Syntax, types, composition
⚡ Concurrency	4-6	Concurrency, Systems, Networking	Goroutines, GC, TCP
🏗️ Production	7-9	Patterns, Production, DSA	Clean code, testing, interviews
🌍 Scale	10-12	Distributed	Kafka, Redis, K8s

Quick Start

go run src/01_foundations/01_hello_world/main.go

Deep Dives

Topic	What You'll Learn
Go vs C++	Philosophy shift, no inheritance, GC vs RAII
Memory & GC	Stack/heap, escape analysis, tri-color GC
GMP Scheduler	Goroutine scheduling, work stealing, preemption
Channels Internals	hchan struct, ring buffer, nil/closed behavior
Interfaces Under Hood	iface/eface, method sets, type assertions
Interview Roadmap	4-week plan, company focus areas

Code Stats

62 compilable Go source files across 10 modules. Every file:

• Has package main + func main() runs independently
• Dual-tone commentary (beginner analogies + C++ comparisons)
• Standard library only no external dependencies
