JavaScript vs Nodejs: The Key Differences That You Must Know

Are you interested in knowing about some key differences between JavaScript vs Nodejs? If yes, then you are at the right place. JavaScript vs Nodejs is always a big concern among the students. Before going deeper, Let’s start with a short introduction to each of these terms.

Introduction To JavaScript

Javascript is a lightweight object-oriented programming language for creating dynamic HTML pages with interactive effects. JavaScript is also widely utilised in the development of games and mobile apps. The code can only be executed and run in a web browser because it is an interpreted scripting language. To execute and run the code outside of the browser, we may utilise Node.js.

It’s also known as a browser’s language, and it’s capable of client-side and server-side programming. It was invented by Netscape’s Brendan Eich and was released in 1995. Before being renamed JavaScript, the language was known as LiveScript. The computer language C had a big effect on JavaScript’s syntax. The filename extension for JavaScript is .js.

Introduction To Node.js

Node.js is an open-source, cross-platform JavaScript runtime environment that allows you to run the JavaScript on the server. JavaScript code may now execute outside of the browser thanks to Node.js. Node.js has a vast number of modules and is mostly used for web development.

It may operate on a variety of operating systems, including Windows, Linux, and Mac OS. It provides a cross-platform runtime environment for developing extremely scalable server-side JavaScript applications with event-driven, non-blocking (asynchronous) I/O.

Ryan Dahl created as well as introduced the Node.js in 2009. Web apps, real-time chat apps, command-line apps, and REST API servers are just a few of the applications that may be built using Node.js. It is, however, mostly used to create network applications like web servers. Node.js’s normal filename extension is .js.

JavaScript vs Nodejs: The Key Differences

JavaScript vs Nodejs: Type

Javascript is a popular programming language that can be used in any web browser. In contrast, Node.js is a JavaScript interpreter and environment with certain special helpful libraries that may be used independently for JS programming.

JavaScript vs Nodejs: Utility

Javascript is mostly used for a web application for any client-side action, such as refreshing the page at a set interval, potential attribute validation, or providing any dynamic changes in web app pages without having to reload the page.

Some of the greatest IT organisations that provide software solutions utilise it to conduct or access any non-blocking operating system action, such as executing or writing a shell script, obtaining hardware-specific information, or running any backend process. 

JavaScript vs Nodejs: Running Engine

JavaScript may run on any engine, including Safari’s JavaScript Core, FireFox’s Spider Monkey, and V8 (Google Chrome)

Node.js is only supported by the V8 engine, which is mostly utilised by Google Chrome. Furthermore, any JS programme developed using the Node.js library will always execute or run in the V8 Engine.

Some More Important Differences Of JavaScript vs Nodejs

  1. JavaScript is a basic programming language that can be used in any browser that has the JavaScript Engine installed. While Node JS is an interpreter or runtime environment for the JavaScript programming language, it requires libraries that can be readily accessible from JavaScript programming to make it more useful.
  2. For a single web application, JavaScript is often utilised for any client-side action. An activity might be dealing with business validation, dynamic page display at a set time period, or a simple Ajax call kind of task. For each online application, they are utilised for a maximum amount of time. In contrast, Nodejs is mostly used for accessing or executing any operating system in a non-blocking manner. On an operating system, a non-blocking action is one that involves creating or executing a shell script, retrieving specified hardware-related information in a single call, obtaining installed certificate data in the system, or performing a large number of defined tasks.
  3. JavaScript is a scripting language that adheres to the Java programming language standard. There may be some differences in the way code is written, but we can say that it adheres to the Java programming language standard. Whereas node JS is designed in C++ and provides a browser javascript runtime engine based on the V8 engine, it allows us to run a written javascript programme in any browser environment. 
  4. Unique non-blocking job JavaScript includes several specific objects to access any operating system, however, they are all operating system specific. For e.g., ActiveX Control is a Windows-only application. However, Node JS is provided with the ability to conduct non-blocking operations related to the operating system from any JavaScript programming. There is no operating system specific constants in it. Node JS is well-versed in creating a particular coupling with the file system, allowing the developer to read and write to disc.

Advantages and Disadvantages of JavaScript vs Nodejs

Advantages and Disadvantages of JavaScript

AdvantagesDisadvantages
  • It is a fast, open-source, flexible as well as a light-weighted framework.

  •  Cross-compilation is allowed in it.

  • Interfaces, modules, and classes are all supported.

  • It’s used for both frontends as well as backend development, allowing it to run on a variety of platforms.

  • It enables us to create user interfaces that respond when the mouse hovers over them.

  • Because of its compatibility with other languages, JavaScript might be used in a variety of other applications.

  • We could expand JavaScript to allow for the creation of big apps.
  • It makes use of a small number of libraries.

  • Client-side Writing and reading files are not supported by JavaScript. 

  • A single mistake might bring the entire website down.

  • Because it is a dynamic language, developers are more likely to commit major errors.

  • It only allows a single inheritance; multiple inheritances are not supported. This object-oriented language feature may be required by some programmes.
  • Advantages and Disadvantages of Nodejs

    AdvantagesDisadvantages
  • js is an open-source framework with an MIT licence.

  • It’s a lightweight framework and it includes the minimum modules. Other modules may be added depending on the application’s needs.

  • It’s a cross-platform framework for Windows, Mac, and Linux.

  • The JavaScript programming language is used to create server-side apps.

  • In apps, js applications never buffered any form of data. Data is produced in chunks by Nodejs apps.

  • All of the APIs in the Nodejs library is asynchronous or non-blocking.

  • js is a fast programming execution library based on Google Chrome’s V8 JavaScript Engine.
  • One of Nodejs’ major drawbacks is its lack of consistency. The API changes on a frequent basis, which complicates things for developers because they’ll have to make adjustments to their existing code base to stay compatible.

  • It doesn’t enable multi-threading programming and isn’t designed for the creation of large-scale computing applications.

  • JavaScript, unlike other programming languages, lacks a comprehensive and functional library framework. As a result, users are compelled to utilise a common library to perform a variety of functions, such as image processing, XML parsing, Object-Relational Mapping (ORM), and database operations, among others. It makes it difficult for developers to use Nodejs for simple programming tasks.
