Node js and Python are not comparable tools. Node js is a run time environment that helps in running JavaScript code outside the web browser i.e. communicate with a server. Python on the other hand is a programming language that basically has infinite potential.  

If you are looking to master Python, which is also used in back-end development, we suggest you check out the Python programming course.

Steps to run Node JS code:  

• Find Command Prompt by entering cmd in the search bar. Select cmd in the search results menu to open Command Prompt.   

• Type the command below and then press “Enter” in order to create a file name “test-node.js” which contains a simple application to print the result of 1 + 1:  

echo console.log(1+1); >> test-node.js  

• Type node followed by the name of the application, given above and then press “Enter”:  

node test-node.js  

• The result of running the application should be printed out in the command prompt.  

In our Node js program, we also cover how to run Node js code in different and more efficient ways like directly from your IDE.

In the MERN stack, Node js is used for back-end. Some JavaScript frameworks designed for front-end development (like React) can be used with Node.js on the server-side for tasks like server-side rendering, which can improve performance and SEO. 

If you want to dive deeper into both front-end as well along with our Node js course syllabus, we have the perfect Full-Stack program for you.

Yes, Node.js versions starting from 17.2 include built-in support for running WebAssembly modules. This means you can directly execute WASM code within your Node.js applications. Node.js support for WebAssembly opens doors for improved performance, code reusability, and potential security benefits in your server-side applications.

Callback hell is a term used to describe a situation in Node.js where you end up nesting multiple callback functions within one another, creating complex and difficult-to-read code. Thankfully there are some approaches to avoid callback hell in Node.js and make your asynchronous code more readable and maintainable like by using promises or Async await functions.  

Head to our free resource to gain a deeper understanding of how to spot and avoid callback hell in your own code.

In the context of Node.js, "Node" refers to the execution environment itself. It's not a separate program or library, but rather the foundation upon which Node.js applications run. 

Enrolling for our Node js training will help you gain a better understanding of the distinction.

Choosing the best Node.js framework depends on your project's requirements and your preferences as a developer. Here are some of the most popular frameworks to consider: 

• Express.js - On top of a set of routing libraries, it provides a few web application features  

• Socket.io - It is designed to establish real-time two-way event-based communication.  

• Sails.js - It is used for developing modern, real-time features like chat. 

Out of these Express.js is extensively covered in our Node js program.

In Node.js, modules are the building blocks of your applications. They are reusable units of code that provide functionalities you can import and use in your Node.js projects. Using modules in Node js streamlines the development process. Our Node js training extensively covers the use of modules in not just in Node js but also JavaScript.

Node.js shines in building a variety of web applications, particularly those that emphasize real-time features, scalability, and data streaming. Here are some categories of applications well-suited for Node.js development:

• Real-time Applications:  Node.js excels at handling real-time interactions due to its event-driven, non-blocking architecture. This makes it a popular choice for applications like chat applications, collaborative editing tools, or live dashboards.

• Single-Page Applications (SPAs):  SPAs are web applications that load a single HTML page and dynamically update the content using JavaScript. Node.js can be a great backend for SPAs, handling server-side logic and data interactions while the frontend leverages frameworks like React or Vue.js.

KnowledgeHut’s Node js certification includes a capstone project in which you will create an application from scratch.

Depending on what you want your application to do, here are some examples of scaling and what they are used for:   

• Horizontal scaling: Duplicating your application so as to cope with large number of incoming connections.  

• Vertical scaling: Used to enhance power and increase memory.  

• Have multiple processes running on the same machine to distribute the incoming connections.  

Scaling Across Multiple Machines with Network Load Balancing where each machine will run one or more processes in order to balance the load across the entire system. Learn more about scaling Node js applications in our Node js full course.

At first, import the ‘data_base’ using the following statement:

let data_base = require('database');

Secondly, establish a connection to the database by calling the createConnection() method and provide information on data_base server such as host, user, password and database as follows:

let connection = data_base.createConnection({host: 'localhost' ,user: 'root' ,password: ' ', database: 'todoapp'});

Here, we created a connection to todoapp database in the local database server.

Now, call the connect() method on the connection object to connect to the data_base database server:

connection.connect(function(err) {

if (err) { return console.error('error: ' + err.message); }

console.log('Connected to the data_base server.');

});

The connect() method accepts a callback function that has the err argument which provides the detailed error if any error occurred.

If the program shows the following result, the program is successful:

> node connect.js

Connected to the data_base server

Node.js is written in C, C++, and JavaScript. 

• Core Functionality: The core functionality of Node.js is written in C++. This lays the foundation for efficient system interaction, memory management, and the event loop that powers Node.js's asynchronous nature. 

• JavaScript Engine:  At its heart, Node.js relies on the V8 JavaScript engine, which is also written in C++. This engine is what allows Node.js to execute JavaScript code outside of a web browser environment.

Node.js stands out as a free and open-source server environment that breaks the mold. Instead of relying on traditional languages for server-side scripting, Node.js embraces JavaScript, allowing developers to use a familiar language across their entire application stack. This flexibility extends to its platform compatibility, as Node.js runs seamlessly on various operating systems like Windows, Mac, OS X, Unix, and Linux.  One of its key strengths lies in asynchronous programming, enabling it to handle multiple requests concurrently without breaking a sweat.

Node.js lets you run JavaScript code outside the browser, on the server. This makes it ideal for building scalable web applications, especially those that need to be real-time or data-intensive. Think chat apps, single-page applications, and streaming services.

Node js is a JavaScript runtime environment that thrives on building real-time features and data-heavy apps.  Imagine constantly updating chat feeds or streaming music? Node.js excels at these tasks. It also scales well for growing user bases and powers the backends of modern single-page applications. So, if you need speed, scalability, and real-time functionality in your web projects, Node.js is a strong contender.

Here is an overview of the evolution of Node js: 

• 2009-2014: Birth of Node.js with a focus on asynchronous processing for simple web tasks. Package management and frameworks were limited. 

• 2014-2018: Explosion of npm for easy module discovery and frameworks like Express.js to streamline development. The community grew, and standardization efforts began. 

• 2018-Present: Performance soared, and features like clustering boosted scalability. Security features improved. Native ESM support and WebAssembly integration arrived. Continuous innovation ensures Node.js stays relevant.

Node.js is neither a language nor a framework! It's a runtime environment. Imagine it as a special engine that lets you run JavaScript code outside of a web browser. This engine is built using various languages like C++, but you write your Node.js applications in JavaScript.  Think of Node.js as a toolbox that provides the tools (libraries, modules) to build different web applications, and JavaScript as the building blocks you use with those tools.

Node.js shines with features that make it great for modern web apps.  

• JavaScript Everywhere: Run JavaScript code outside the browser, on the server-side, for a unified development experience. 

• Asynchronous & Non-Blocking: Handles multiple requests concurrently without waiting, ideal for real-time apps and data-heavy tasks.
