Grin With Golang 🐹¶
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¶
# Automated setup (recommended for first time)
git clone https://github.com/GauravAgarwalGarg/grin-with-golang.git
cd grin-with-golang
chmod +x scripts/setup.sh && ./scripts/setup.sh
# Or just run an example
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)
- Modules 01–09 use standard library only; Module 10 uses external deps (Kafka, gRPC, MongoDB, etc.)
