Master Go (Golang): Build Scalable Web Applications

Explore Go syntax and structure by building a simple program that demonstrates package declaration, main function, imports, variables, constants, and basic printing, highlighting Go's static typing, simplicity, and concurrency features.

Explore variables, constants, and data types in Go. Learn how to declare and initialize values, and print them using strings, integers, floats, and booleans.

Practice printing and reading input in Go using fmt, including Println and Scan, to capture user input and display results.

Explore basic operators and expressions in Go, including arithmetic, relational, and logical operators, with practical examples using variables and print statements to build functional code.

Learn to make decisions in Go using if else and switch statements, test numbers with modulo for even or odd results, and handle multiple cases with default blocks.

Master Go teaches you to use for and range loops to iterate over numbers and collections, print values with fmt, and perform repetitive tasks efficiently in scalable web applications.

Explore Go's unique approach to loops, including basic for loops, infinite loops, and range iterations over maps and slices, to build scalable web applications.

Learn to declare and call functions in Go, print messages from a simple function, and use parameters for addition and other calculations from the main function.

Master Go's no-exception error handling by using the error type, learn to create and return errors, and build clear messages with fmt error for division by zero and other errors.

Explore how pointers in Go store memory addresses, enable in-place updates, and improve memory management by passing pointers to functions to avoid copying.

Master the defer statement for delayed execution and resource cleanup, and learn to use panic and recover to handle errors and regain program control.

Explore Go arrays and slices, compare fixed-size arrays with flexible slices, and learn best practices for declaring, indexing, appending, and printing data.

Learn to create and initialize maps in go, store key-value pairs, and access or update values to manage data such as person names and ages.

Explore how to define and use custom data types in Go using structs, including examples of person and book types with fields like name, age, title, author, pages, and published.

Discover how Go uses structs and methods to implement object-oriented behavior, define a card type with brand, model, and year, and display details and update via a pointer receiver.

Explore interfaces in Go by implementing polymorphism across circle and rectangle types, enabling a shared area calculation through a common interface.

Learn how goroutines enable lightweight concurrent execution in Go, launch routines with the go keyword, and observe concurrent tasks like A and B running together with sleep delays.

Learn how to use channels in Go to enable communication between goroutines, including creating, buffering with capacity, sending and receiving values, closing channels, and iterating with range.

Learn to read and write files in Go using os and io packages, with practical examples that demonstrate creating, writing to, and reading from example.text.

Learn to handle json and xml data in Go by encoding and decoding with encoding/json and encoding/xml, using book and person examples to illustrate structs and tags.

Learn to handle file errors gracefully in Go by opening, creating, and writing to files with proper error checks, printing errors, and deferring close.

Learn how to connect a Go application to a SQLite database using the sqlite3 driver, open and verify the connection, execute basic statements, and close the database safely.

Learn how to use Go's database/sql package with drivers to connect to MySQL, PostgreSQL, or SQLite, create a database handle, and open and verify connections.

Learn to implement create, read, and update operations in Go with MySQL and PostgreSQL, including database connection, query execution, and handling results for a users table.
