GO Programming: The Complete Guide to Golang Development

Explore how Go handles data types such as integers, floats, strings, and booleans with practical examples and type conversions. Use fmt to print results and run programs with go run.

Explore operators and expressions in Go programming, including arithmetic, comparison, logical, and assignment operators, with practical examples and compound assignments.

Explore Go functions, including defining functions with parameters and return values, and learn how the defer keyword delays execution to support cleanup.

Explore the Go range keyword to iterate over slices, maps, strings, and channels, accessing index and value, printing results, and using the underscore to ignore values.

Master iteration best practices in Go by using for range with underscore to ignore unused index, and break for early exit. Learn that map iteration order is unordered.

Explore defining a custom stack using structs in Go, with fields like name and age, and demonstrate creating, updating, and printing stack elements via dot notation.

Explore how to define struct tags for Go structs, encode data to JSON with json tags, skip fields, and decode JSON into Go structures using the encoding/json package.

Learn to define methods on structures with value and pointer receivers, and attach them to types like circles. Master using interfaces and empty interfaces with type assertions to access values.

Master embedding and composition in Go to reuse code without inheritance, demonstrating stack embedding, promoted logger methods, and interface-based document printing with dynamic behavior injection.

Master pointers in Go by declaring and dereferencing, printing addresses, and using pointers to modify values and struct fields, including updating a person’s age by reference.

Explore value versus reference types in Go, illustrating int copy on assignment, struct copies, and how slices and maps behave as reference types to prevent bugs and improve code predictability.

Explore how Go manages memory with automatic garbage collection, including new allocations, short-lived data, escape analysis, and optional manual GC triggering.

Explore Go's error handling by using the classic return-value pattern, create errors with errors.New and wrap with fmt.Errorf, and propagate config and init app errors to preserve context.

Study Go error handling from basic errors to wrapped errors with fmt.Errorf, including username validation, file open failures, and unwrapping errors for context.

Explore how panic and recover control Go program flow, differentiate proper and improper use, and see how recover preserves execution across nested function calls.

Explore Go routing, a lightweight concurrency feature managed by the Go runtime, learn to launch, print, and sleep across concurrent tasks with for loops and anonymous functions.

Explore unbuffered and buffered channels in Go, learn sending and receiving with goroutines, and observe buffering effects, capacity, and proper channel closing to avoid deadlock.

Master go concurrency by using mutexes and wait groups to safely manage shared data across multiple goroutines, preventing race conditions and coordinating completion.

Learn to read and write files in Go using the os package, including creating and writing to text files like example.txt, appending content, and reading data back with error handling.

Explore how to read and write data efficiently in Go using the io and bufio packages, including buffered writing, writer flush, and file copy with io.Copy.

Learn to process json and csv data in Go by encoding and decoding json with structs, marshaling and unmarshalling, and reading csv files to write reports.

Explains go modules as the official standard for go 1.16, showing how to create a go.mod with a mod path, add dependencies, and build a multi-package module with external packages.

Learn how Go packages organize code into reusable modules, create a utility package with an add function, import it in main, and define a person struct with a greet method.

Explore Go (Golang), a statically typed, high-performance language with built-in concurrency and a powerful standard library, for building scalable web applications, including HTTP servers, routing, middleware, and JSON handling.

Explore building a Go http server with the net/http package, creating routes and handlers, and making get requests to illustrate basic endpoints like root, about, and contact.

Explore routing in Go using the Gorilla Mux package, define routes with parameters, create handlers, and run a server on port 8080.

Build a Go http server that handles json post requests, decodes input, and prints a receipt. Return a json response with a status code and message.
