Getting Started with V Programming

Chapter 7: Functions

So far, throughout this book, we have learned about the basic programming features of V, including arrays, maps, conditionals, and iterative statements. It's time for us to learn about writing functions in V. Most programmers, when writing software applications, prefer to group a set of statements such as variable declarations and perform arithmetic or logical operations with them, or iterate over the elements of an array or map and then filter them according to their need.
