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
let 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);
