Go Composite Types and Command-Line Applications

Go is known for its simplicity and powerful standard library, but mastering how to structure and handle complex data is key to writing efficient applications. This course teaches you the foundational concepts of composite data types—arrays, slices, maps, and structs—and how to apply them to real-world tasks, including handling external input from the command line. You will gain the skills necessary to manage structured data effectively in any Go project. What you'll learn: * Understand the differences between arrays, slices, and maps, and when to use each for optimal data storage. * Define and utilize custom structs to model complex entities and ensure type-safe data handling. * Apply modern Go error handling patterns when manipulating composite data and processing external input. * Practice converting and transforming structured data, such as mapping complex lists of data into key-value pairs. * Configure and parse arguments and flags using standard library packages to build functional command-line utilities. * Learn how to structure a modern Go project using Go Modules for dependency management. The course begins with defining fundamental data structures and their behavior, progressing through practical exercises on data manipulation, custom type creation, and robust input processing. We emphasize idiomatic Go practices throughout the material. This course is designed for absolute beginners in Go programming. No prior knowledge of Go or advanced data structures is required.
