Node.js Process Complete Reference

A process object is a global object that gives information about and controls the node.js process. As it is global, it can be used in the project without importing it from any module. 

Example:

Javascript

// Node.js program to demonstrate the
// process.versions property

// Include process module
const process = require('process');

// Printing process.versions property value
// and variable count
const no_versions = 0;

// Calling process.versions property
const versions = process.versions;

// Iterating through all returned data
for (let key in versions) {
    // Printing key and its versions
    console.log(key + ":\t\t\t" + versions[key]);
    no_versions++;
}

// Printing count value
console.log("Total no of values available = " + no_versions);
