What is the Difference between Node.JS and JavaScript?
FREE
The server-side execution of Javascript is made possible via NodeJS, a cross-platform, open-source Javascript runtime environment. Javascript code can run outside of the browser with the help of Node.js. Some modules are included with Nodejs, which is primarily used for web development. While on the other hand, Javascript is a Scripting language. JS is the most common abbreviation. We can say that Javascript is an upgraded version of the ECMA script. Although it is built on prototype inheritance, the high-level programming language Javascript uses the Oops concept.
Below are some differences between Node.JS and JavaScript:
| S. No. | Node.JS | JavaScript |
|---|---|---|
| 1 | NodeJS is a Javascript runtime environment. | Javascript is a computer programming language that is used to build scripts for websites. |
| 2 | With the support of NodeJS, Javascript can be executed outside of the browser. | Only browsers are capable of running Javascript. |
| 3 | Server-side development makes use of Node.js. | Front-end development makes use of Javascript. |
| 4 | On the server side, Node.JS is primarily utilised. | Client-side applications primarily require Javascript. |
| 5 | HTML tags cannot be added using Node.js | Javascript is powerful enough to interact with the DOM and add HTML. |
| 6 | Javascript is run on V8, which is a component of node. Javascript running and parsing js. | Any browser engine, such as JS core in Safari and Spidermonkey in Firefox, may run Javascript. |
| 7 | Javascript, C, and C++ are used to create Node.js. | The C++ written V8 engine in Chrome is used in this updated version of the ECMA script. |
What is Node.js?
Node.js was created by Ryan Dahl and premiered in 2009. Node.js is an open-source JavaScript runtime environment that can be used to execute JavaScript on the server. Now, JavaScript code can run independently outside of a browser. Node.js is widely used for web development and contains a large number of components. It might function on other Operating Systems, such as Windows, Linux, and Mac OS. It offers a cross-platform runtime environment for creating server-side JavaScript applications with extremely scalable I/O that is event-driven and non-blocking (asynchronous).
The Benefits and Drawbacks of Node.js
Benefits:
The benefits of node js vs javascript are as follows:
- Node.JS is an open-source run time environment with an MIT license.
- Node.JS is a minimal framework that only includes the most crucial modules. Depending on the needs of the application, other components might be added.
- It is a cross-platform framework that works with Linux, Mac OS X, and Windows.
- The main point between node js vs javascript. Js programs never buffered any type of data. Node.js apps produce data in chunks. All of the interfaces in the Node.js library are reactive or non-blocking. Data from such an API is never awaited by the Node.js host. We can see it well now. A Node.js notification system assists the server in receiving a response from the previous API request before moving on to the next API.
- Server-side applications are made with the JavaScript programming language.
- A programming library with quick execution called JavaScript is based on the V8 JavaScript Engine.
Drawbacks:
The drawbacks of node js vs javascript are as follows:
- Lack of consistency is one of the main problems with Node.js. Developers face difficulties as a result of the API's frequent updates because they must update their existing code base to remain compliant.
- In contrast to other programming languages, JavaScript lacks a robust and functional library framework. Users are thereby compelled to use a shared library in order to carry out operations on databases, process XML, process picture data, and process Entity data. It makes using Node.js for basic programming tasks challenging for developers.
- It is inappropriate for developing high-performance computing applications since it does not support multi-threading programming.
What is JavaScript?
Brendan Eich of Netscape created the initial version of JavaScript, which was released in 1995. (then called LiveScript). A straightforward object-oriented programming language for creating interactive HTML pages is called Javascript. JavaScript is commonly utilized in the creation of mobile games and applications. The application is interpreted as scripting and can only be run in an internet browser.
The Benefits and Drawbacks of JavaScript
The following are examples of JavaScript's advantages and disadvantages:
Benefits:
- It is a lightweight, quick, and versatile open-source framework.
- In javascript, cross-compilation is feasible.
- We could improve JavaScript to make it possible to create useful applications.
- It can run on several platforms because it can be used for both frontend and backend development.
- Javascript supports classes, modules, and interfaces.
- We can develop user interfaces that respond when the mouse has hovered over them.
- With other languages, it functions nicely. As a result, it has a wide range of different applications.
Drawbacks:
- Libraries are not extensively used by JavaScript.
- Client-side JavaScript does not support reading or writing files. Only security concerns have led to its preservation.
- A single error in JavaScript might take down the entire website.
- Due to the dynamic nature of JavsScript, developers are more likely to make significant mistakes.
- Various inheritances are not supported by JavaScript; only single inheritance is supported by JavaScript. This characteristic of object-oriented language might be necessary for some programs.
Key Differences between JavaScript vs Node JS
| Key | JavaScript | Node.JS |
|---|---|---|
| Type | JavaScript is a high-level programming language. Any web browser with an appropriate browser engine can run it. | It is a JavaScript interpreter and environment that includes certain important, specialized libraries that JavaScript programming can utilize independently. |
| Utility | Primarily used for any client-side operation for a web application, such as potential attribute validation, periodic page refreshes, or availability of dynamic changes in web pages without refreshing the page. | It is mostly used for accessing or executing any non-blocking operating system operations, such as writing or running a shell script, getting access to hardware-specific data, or doing any backend tasks. |
| Running Engine | JavaScript running on any engine, such as V8(Google Chrome), Spider Monkey (FireFox), and JavaScript Core. | Only the V8 engine, which is mostly used by Google Chrome, can run Node JS. Additionally, any JavaScript programs created with Node JS will always be run in the V8 Engine. |
| Execution | JavaScript is executed in the browser | We can use Node.js to run JavaScript code outside of a browser. |
| Capability | JavaScript has the ability to add HTML or manipulate the DOM. | HTML embedding is not supported by Node.js. |

Conclusion
- A high-level, lightweight (simple syntax), object-oriented programming language called JavaScript is used by basically all web developers to build web pages, web apps, mobile applications, and video games.
- Node.js is a JavaScript runtime environment that is used to run JavaScript outside of a browser and is based on Google's v8 engine.
- JavaScript is executed on the browser whereas Node.JS is used to run JavaScript code outside of a browser
- JavaScript has the ability of DOM manipulation whereas Node.JS doesn't the ability of DOM manipulation.
- Node JS is an extension of the JavaScript framework that also has other unspecified characteristics, like a non-blocking running control system, that is crucial for achieving organizational goals.
