Setup

• Installed Go and verified go version
• Configured editor with Go tools (format on save, lint, test)
• Initialized a module with go mod init

Language Basics

• First Program compiles and runs
• Print output with fmt.Print/Println/Printf
• Comments and doc comments (go doc)
• Types & Keywords (zero values, type aliases)
• Variables & Constants (var, const, :=)
• Operators (arithmetic, comparison, logical)
• Naming conventions & style (exported names)

Control Flow

• if/else (with short statements)
• switch (type/value, fallthrough)
• for loops (classic, range)
• break/continue
• defer / panic / recover

Data Structures

• Arrays vs Slices—append, subslicing, capacity
• Maps—existence checks with v, ok := m[k]
• Structs—literals, tags, embedding
• Methods & receivers—value vs pointer
• Interfaces—implicit satisfaction, small interfaces
• Generics—basic constraints and functions
• Pointers—address, dereference, when to use

I/O & Data Formats

• Read and write files (os.ReadFile/WriteFile)
• Streaming I/O with bufio.Scanner
• JSON encoding/decoding with tags

Error Handling & Concurrency (Intro)

• Idiomatic error handling patterns
• Basics of goroutines and channels
• Using context for cancellation/timeouts

Tooling & Tests

• go fmt, go vet, and linting
• go test—table tests, coverage
• Modules & dependency management

Capstone Readiness

• Build a small CLI or HTTP service
• Read config, log, and handle errors properly
• Write basic unit tests for core logic
