Handle user input in console in NodeJS

Node.js is a cross-platform JavaScript runtime surroundings and library. It runs web applications outside the client's browser. 

Node.js is very good at handling simultaneous connections. Node.js makes a terrific backend for those applications. It provides serverless architecture and real-time communication support. It handles the quick processing of small messages sent by many devices in IoT. We must use formData to send your added element to your backend node.js and use jQuery $. Each characteristic receives all the values of the enter you may add. To access the element, the JavaScript method document, we should use getElementById. This characteristic expects to get the ID of the detail as an argument. You can now use the cost assets of the again item to get entry to the cost of the enter element.

Here is an example of how to handle user input in the console in Node.js:

Instructions

Follow the steps carefully to get the output easily.

1. Install Node and Visual Studio Code on your computer.
2. Create a new folder in your local.
3. Open that folder in Visual Studio Code.
4. Then create a new JS file(Eg: node.js).
5. Copy the snippet using 'copy' button and paste it into that file.
6. Save the file and open the terminal, use this command 'node filename(node.js)' to get the output in your console.

FAQ 

1. What is Node.js used for? 

As a backend runtime for web applications, developers use Node.js. It permits builders to execute JavaScript code on the server side. This makes it efficient for handling simultaneous connections and supporting serverless architecture. 

2. Why is Node.js suitable for real-time communication? 

Node.js excels in handling asynchronous tasks. It is ideal for real-time applications. Its event-driven architecture enables efficient communication between the server and clients. This makes it a preferred choice for applications requiring instant updates. 

3. How does Node.js contribute to IoT development? 

Node.js is well-suited for IoT (Internet of Things) applications. It can process small messages sent by many devices. It's good for IoT because it's light and can handle many connections at once without getting stuck. 

4. Why use formData in Node.js for sending data to the backend? 

Using formData simplifies the process of sending structured data to a Node.js backend. It allows developers to handle and parse form data. This makes it convenient for the client to submit information to the server. 

5. Why choose getElementById in JavaScript for accessing DOM elements? 

getElementById is a fundamental JavaScript method. The Document Object Model (DOM) uses it to access elements. It is efficient and straightforward, requiring the ID of the element as an argument. Developers use this method to interact with specific elements on a webpage. They use it particularly when retrieving values from input elements.
