Intro

Intro

Intro is a core part of Node.js. In this case file you'll learn what it is, why it matters, and how to use it in real code.

Understanding intro well means you can read other people's Node.js code with confidence, and avoid the most common beginner mistakes in this area.

Key points:

• What intro means in the context of Node.js
• A minimal example you can run or read in the playground on the right
• A common mistake to avoid when working with intro

// Node.js: Intro
function demo() {
  console.log("Exploring Intro in Node.js");
}

demo();

Tip: Try changing a value in the code on the right and re-running it — small experiments are the fastest way to build real intuition for intro.
