Model data and behaviour with Go's type system by defining structs, attaching methods, and designing with interfaces. You will learn embedding and composition, when to use pointer versus value receivers, how implicit interface satisfaction works, and how to encapsulate state cleanly — so you can honestly design idiomatic Go types on the job.
Learn to write core Go syntax fluently — declaring variables, choosing basic types, defining constants with iota, and steering programs with if, switch and Go's single for loop. You finish able to read and write small, idiomatic Go programs with functions, multiple return values, packages and fmt formatting, ready to tick "write core Go syntax" on any back-end role.
Install the Go toolchain, initialise a module, and write, run and build your very first Go program with confidence. You will learn the everyday go commands, how modules replaced GOPATH, sensible project layout, and where to reach in the standard library.
Learn to structure Go code into reusable pieces — functions with multiple returns, closures, variadics and defer, then packages and modules that organise and version your code. You will finish able to split a program into clean, importable packages and manage its dependencies with go modules.
