Enable JavaScript for Running this App in Node.js

I will discuss enabling JavaScript for running an app in Node.js.

Setting Up and Configuring Web Servers

To enable JavaScript for running an app in Node.js, you need to set up and configure your web server correctly. First, make sure Node.js is installed on your system. Then, create a new directory for your project and navigate to it in your terminal.

Next, initialize a new Node.js project by running the following command: npm init -y. This will create a package.json file for your project. Install Express, a popular Node.js web framework, by running npm install express.

Create a new JavaScript file for your server, for example app.js, and require Express in it. Set up a basic server using Express and listen on a specific port, such as 3000. Run your server by executing node app.js in the terminal.

Finally, open your web browser and navigate to http://localhost:3000 to see your app running. Make sure JavaScript is enabled in your browser settings to ensure your app functions correctly.
