Go Language

What’s inside

• Foundations — Setup, variables, types and zero values, console I/O with fmt, operators, conditionals and switch, and loops
• Data — Arrays and slices, maps and structs, and strings, runes and UTF-8
• Functions & Types — Functions and multiple returns, pointers, methods and receivers, composition and embedding, and interfaces
• Robustness — Errors as values, defer, panic and recover, packages and modules, files and JSON, and generics
• Concurrency — Three full chapters: goroutines, channels, and select with the core concurrency patterns
• Professional Go — Testing and benchmarking, dates and time, the standard library and net/http, the main libraries, built-in functions, and data structures
• Runnable code, trap-annotated — the idiomatic way and the classic traps met in safety first, with a practice challenge and a harder bonus in every chapter
• 5 Capstone Projects — TaskTrek, WordWeave, Pulse, Minnow, and an RPN calculator, each with a full Solutions & Explanations chapter
