Understanding function types
In this section, we will examine the different types of functions that can be written in V. We will begin with the basic or most commonly written function based on the syntax that we just learned. Then, we will take a look at how to write anonymous functions that do not have any function name and explore various ways in which we can work with anonymous functions. Following this, we will learn how to create functions that accept other functions as input arguments and look at functions that return other functions as their return types, which are often referred to as higher-order functions.
The main function
To begin, let's start with the main function. This function is the entry point in a V file or a project with multiple V files or modules inside it. Whenever you run the file using v run filename.v or a project using the v run . command, the execution control looks for the presence of the main function and starts from there. However, there are...
