Implementing concurrency in V

Using V, you can write a program that runs functions concurrently using the go keyword. The go keyword is a built-in keyword in V. The go keyword is available anywhere in the program without any explicit import statements required. In the next section, we will understand the basic syntax of the go keyword.

The go keyword syntax

You can run any function concurrently using the go keyword, just by writing the go keyword followed by the name of the function, as shown here:

go FUNCTION_NAME_1(OPTIONAL_ARGUMENTS)

In the preceding syntax, which demonstrates the usage of the go keyword in V, all we can see is a simple function named FUNCTION_NAME_1 that is being run concurrently. You do not need to make any special syntactical changes to a function to run it concurrently.

With the approach mentioned in the preceding syntax, the active program spawns a new thread and lets the function run concurrently. If the active program is interested in knowing...
