Go Programming

Build scalable backend systems with Go. Cover goroutines, channels, interfaces, error handling, and real-world API development patterns.

Lessons

  1. Introduction to Go — Learn why Go was created, how to set up your development environment, and write your first Go program.
  2. Variables & Types — Understand Go's type system, variable declaration styles, zero values, type inference, and constants.
  3. Functions & Methods — Master Go functions including multiple return values, variadic parameters, closures, and methods on types.
  4. Control Flow — Learn Go's control flow statements including if, for, switch, defer, and range.
  5. Arrays, Slices & Maps — Work with Go's fundamental collection types: fixed-size arrays, dynamic slices, and hash maps.
  6. Structs & Interfaces — Define custom types with structs, implement polymorphism through interfaces, and use embedding for composition.
  7. Error Handling — Master Go's explicit error handling approach with the error interface, custom error types, wrapping, and sentinel errors.
  8. Goroutines & Channels — Explore Go's concurrency primitives: goroutines for lightweight threads, channels for communication, and sync utilities.
