Go – Introduction to Programming (GO1)

Programming, Rust

Learn a compact, pragmatic language for building server systems and cloud platforms. Go combines native performance and efficient concurrency with developer-friendly simplicity, giving faster iteration than C/C++ and better runtime than many scripting languages used for prototypes.

Practice Go without manual memory management while keeping solid performance; explore the garbage collector, the Go memory model and goroutines and channels for scalable concurrency. Learn the go toolchain, modules, formatting and testing to produce robust cloud services.

The course:

Hide detail
  • The Go programming language
    1. Ecosystem and tools: go toolchain, go mod, workspace, gofmt, govet
    2. Language characteristics, runtime, GC, basic Go memory model
    3. Project structure and common conventions
  • Input, output and the first program
    1. package main structure, func main()
    2. Formatted output (fmt), reading stdin, file I/O (os, bufio)
  • Data types and working with values
    1. Basic types, rune and UTF-8, string handling
    2. Collections: array, slice (capacity vs length), map
    3. Type conversions, iota, constants vs variables
  • Control flow
    1. Conditions, loops, switch (including type switch), defer
    2. Errors as values: error type, creating and wrapping errors, errors.Is/errors.As
  • Functions and interfaces
    1. Multiple return values, named returns
    2. struct, methods on types, interface and implicit implementation
    3. Composition (embedding) instead of inheritance
  • Modules, testing and quality
    1. go mod init, versioning, replace, vendor
    2. go test, table-driven tests, benchmarking (testing.B), fuzz test examples
