node run parameters

// Sample Node.js script to explain run parameters

// Importing the 'process' module from Node.js
const process = require('process');

// Accessing command line arguments using process.argv
const args = process.argv;

// Printing the command line arguments
console.log('List of command line arguments:');
args.forEach((val, index) => {
  console.log(`${index}: ${val}`);
});

Explanation:

  1. Import the 'process' module from Node.js: const process = require('process');
  2. The 'process' module provides information about the current Node.js process.

  3. Access command line arguments using process.argv.

  4. process.argv is an array that contains the command line arguments.
  5. The first two elements of process.argv are:

    • process.argv[0]: The path to the Node.js executable.
    • process.argv[1]: The path to the executed script.
  6. Store command line arguments in the args array: const args = process.argv;

  7. Iterate through the args array and print each command line argument using console.log(): javascript args.forEach((val, index) => { console.log(`${index}: ${val}`); });

  8. This loop prints the index and value of each command line argument in the format index: value.
