Programming language notes for Go — types, concurrency, interfaces, error handling, and package management.

Notes

Go Basics — static typing, zero values, multiple return values, and package structure
Go Control Flow — if/switch/for, defer, panic/recover patterns
Go Functions — first-class functions, closures, variadic params, multiple returns
Go Pointers — pointer semantics, value vs pointer receivers, nil safety
Go Structs — struct embedding, anonymous fields, and composition over inheritance
Go Interfaces — implicit implementation, empty interface, type assertion, type switches
Go Generics — type parameters, constraints, comparable, generic data structures
Go Collections — slices, maps, channels, and idioms for each
Go Errors — sentinel errors, errors.Is/As, custom error types, fmt.Errorf wrapping
Go Concurrency — goroutines, channels, sync.Mutex, WaitGroup, select, context cancellation
Go Packages — module system, go.mod, import paths, and workspace management
