Golang Fundamentals: Learn the Basics of Go Programming

Learn how to install Go on a MacBook using brew, including running auto updates during installation and verifying the setup with go version to display the installed Go version.

Learn to write a hello world program in Go by using package main and func main. Print the message with fmt.Println and run go run main.go to see the output.

Learn Go syntax and structure by exploring package declarations, imports, and functions, and see how a simple program uses package main, import fmt, and fmt.Println to print hello world.

Learn four common ways to declare and initialize variables in Go: var with inferred value, var with explicit type, multiple variables on one line, and print results with fmt.Println.

Explore Go basic data types by declaring integers, floating-point numbers, strings, and booleans, then print them with fmt.Println to see their runtime output.

Learn how to reveal a variable’s data type in Go using fmt.Printf with %T, illustrated with string and integer examples, and run Go programs to see the type outputs.

Learn how to implement conditional logic in Go using if-else and switch, with practical examples of greater than, less than, equal, and default cases.

Explore arrays and slices in go, highlighting fixed-length arrays, out-of-bounds errors, and the ability to append values in slices with runtime flexibility.

Learn how to implement for loops in Go with initialization, condition, and increment, including range loops over slices to access index and element.

Define and call functions in Go using the func keyword, import fmt, and print outputs with fmt.Println in main.go, demonstrated by example messages.

Learn how to define functions with return values in Go, store results in variables, and print outputs using fmt, with examples of string and integer returns and simple if-else logic.

Organize Go code into packages by importing the fmt package and calling its functions with dot notation, such as printing Hello World, and understanding capitalization rules for exported functions.

Learn how to work with pointers in Go by printing a variable's address and its value using fmt and println, illustrating address passing between variables in Go programming.

Explore memory allocation and declaration in Go, where garbage collection automates memory management for variables and composite structures like arrays, slices, maps, and structs.

define and use structs in go to group diverse data types into reusable data structures, with example fields like name, age, and address and creating instances via fmt.Println.

Define a struct in Go and attach methods to compute the area from width and height, returning the value. Print the results with fmt.Println and demonstrate Go run main.go.

Explore encapsulation and data abstraction in Go by using a counter struct, its increment method, and a get counter function.

Learn to write Go functions that return a result and an error, handle errors with errors.new, check for nil, and print either the result or the error.

Explain how panic halts code execution in Go and how defer and recover enable handling panics, triggering prints like recovery messages and resuming after a panic.

Explore goroutines and parallelism in Go by launching multiple goroutines with the go keyword, printing messages, and observing that execution order may vary.

Explore channels in Go, sending and receiving values with Go routines, and learn about buffered versus unbuffered channels, observing outputs with time sleep and print.

Coordinate multiple goroutines using wg.Add and wg.Done to manage concurrency in Go. Protect shared data with mutex.Lock and mutex.Unlock to ensure thread-safe operations.

Learn how to read and write files in Go, including writing 'Hello World' to a file named example.txt, handling errors, and reading back the file content.

Compare TCP and UDP, detailing reliability, ordering, and flow and congestion control. Identify use cases from file transfer to real-time apps like video streaming and online gaming.
