Combine import, package.json and console.log to write your first Node.js program.
Summary - Node.js basics
In this group you saw the basics of Node.js: running files with the node command, writing output with console.log, sharing code with ES modules, managing projects with package.json and the difference between CommonJS and ESM.
Now there are two small tasks that bring these together. First a greeting message, then a two-line output.
Ready? Let us start.
Practice Write a greeting
Write two console.log calls: the first prints Node.js is running, the second prints Version 22.
Starter code
// Write two greeting linesSample solution
console.log("Node.js is running");
console.log("Version 22");Expected output
Node.js is running Version 22
Practice Two-line output
Assign the string "calculator" to a variable named app. Then call console.log with app; on the next line call console.log with "v1.0".
Starter code
// Define app and print two linesSample solution
const app = "calculator";
console.log(app);
console.log("v1.0");Expected output
calculator v1.0
