This guide treats learning to code like building a sandcastle—simple, fun, and free of "grumpy, slow compilers". It introduces concepts like mut (mutable variables) to show how V encourages safety but allows flexibility when needed.
greet('John') // Output: Hello, John!
result := divide(10, 2) or println("Error: cannot divide by zero") return
name := 'V' // immutable mut age := 3 // mutable age = 4 // OK // name = 'New' // Error! This comprehensive guide serves as your roadmap to
The book is organized into several key sections and covers the following topics:
fn divide(a int, b int) ?int if b == 0 return none // Option type indicates possible failure To compile a standalone binary: For editing existing
// Array iteration numbers := [1, 2, 3, 4, 5] for num in numbers println(num) // Custom range loop (0 to 4) for i in 0 .. 5 println(i) // Conditional loop (while-loop equivalent) mut active := true for active println('Running...') active = false Use code with caution.
