Command Line Arguments with process.argv
In this lab, you'll learn about and practice working with command line arguments in Node.js using
process.argv. Command line arguments are the parameters passed to a script during execution. They allow users to provide input or configuration options directly when running a script. This concept is crucial for creating flexible and dynamic Node.js applications that can be configured and adjusted without having to hard-code any values in the script.
process.argv array contains the command-line arguments passed while running the script. The first element (
process.argv) always contains the node executable's path. The second element (
process.argv) will be the script's path. The rest of the elements will contain any additional arguments passed, in the order they were provided.
