Go Fundamentals: Working with Numbers and Collections

Ready to build a strong foundation in Go but feel overwhelmed by syntax details? Understanding how Go handles numeric types and data collections is the critical first step to writing clean, high-performance code. This text-based course guides you through Go's type system, teaching you how to safely convert between numeric types and efficiently manage data using arrays, slices, and maps. You will learn the mechanics behind memory allocation and collection behavior so you can write idiomatic Go code with confidence. What you'll learn: Understand Go's strict type system and foundational numeric types; Convert between integer and floating-point types safely using built-in functions; Manage sequential data using arrays and dynamic slices; Optimize slice performance using the make function and capacity planning; Store key-value pairs efficiently using maps; Apply modern Go best practices for handling collections and preventing common runtime errors. You will start with core definitions and basic numeric types before moving on to practical type conversion scenarios. From there, you will explore collection types, building up from rigid arrays to flexible slices and key-value maps. This course is designed for absolute beginners to Go and developers transitioning from other languages who want a solid grasp of Go's fundamental data structures. No prior Go experience is required.
