The following steps will guide you through the process of creating a "Hello World" application using Express.js:

1. Create a new directory for your project and navigate into it.

2. Install Express.js using npm:

3. Create a server.js file in the root of your project directory and open it in your code editor.

4. Import Express.js into your server.js file:

const express = require('express');

5. Create an instance of Express.js in your server.js file:
