# Rapid Technology Stack Learning Framework

## When to use
Use this skill when switching jobs, adopting a completely unfamiliar language (e.g., Python engineer moving to Rust), learning a new framework under tight deadlines, or evaluating new tooling.

## Core principles
- **Map to Familiar Primitives**: Programming languages share identical underlying concepts: memory management, concurrency models, type systems, and I/O. Learn by translating from what you already master.
- **The Five Core Syntax Anchors of Any Language**:
  1. *Variables, Control Flow & Error Handling* (How do exceptions/errors propagate?).
  2. *Data Structures & Collections* (Arrays, Hash Maps, Sets, Slices).
  3. *Type System & Memory Model* (Static vs. Dynamic; Garbage Collected vs. Manual/Borrowed).
  4. *Package Ecosystem & Build Tooling* (How do dependencies install, compile, and run?).
  5. *Concurrency & Async Primitives* (Threads, Event Loop, Coroutines, Channels).
- **Build Real Toys, Not Passive Tutorials**: Watching 40 hours of YouTube tutorials produces zero retention; building a working CLI tool or HTTP microservice within 48 hours builds permanent neural pathways.

## Step-by-step workflow
1. **Set up a clean local environment**: Install compiler/runtime, language server (LSP), and test runner within 2 hours.
2. **Translate a standard "Rosetta Stone" project**: Implement a simple, familiar project you know by heart (e.g., a CLI todo manager or HTTP rate limiter) in the new language.
3. **Read idiomatic source code**: Read the standard library or top open-source repositories to absorb naming conventions and idioms.
4. **Intentionally trigger compiler errors**: Break types and syntax to learn how the compiler talks and how to interpret error messages.
5. **Ship a production-grade pull request**: Write clean, idiomatic code with unit tests adhering to community style guides.

## Behavioral guidelines & dialogue examples
- **Language Rosetta Stone Mapping**:
  - *Python `try/except`* -> *Rust `Result<T, E>` with `?` operator*.
  - *Node.js `Promise.all`* -> *Go `sync.WaitGroup` with goroutines*.
  - *Java `interface`* -> *Go implicit interfaces or Rust `trait`*.

## Common mistakes & pitfalls
- Writing Python-flavored code in Go, or C++-flavored code in Rust, fighting the language's native paradigms.
- Reading entire language reference manuals cover-to-cover before writing a single line of executable code.
- Skipping package management and debugging tooling, getting stuck on basic environment configuration.

## Verification checklist
- [ ] Language features are mapped to familiar architectural primitives.
- [ ] A concrete working prototype is built and tested within the first 48 hours.
- [ ] Idiomatic conventions and community formatting tooling (e.g., `gofmt`, `cargo fmt`) are adopted.
- [ ] Error handling idioms are internalized and practiced.
