What is the difference between JavaScript and Node.js?

javascript language

JavaScript is a language that runs inside web browsers as part of documents loaded by the browser. It gives behaviour to your pages (HTML gives semantic structure, CSS gives form or look and feel). However nothing ought to restrict JavaScript to run solely inside the browser. Now being an interpreted language, it needs an interpreter to run. V8 is the Google Chrome JS engine and 'node' is a front-end to it that can be used to run JavaScript scripts outside the browser. Node.js or just Node usually refers to a collection of objects and methods available to your JavaScript code when run in V8 or through the node interpreter. It is a JavaScript libray cum runtime.
If you know Java then Java is to JRE is to JVM what JavaScript is to Node is to V8

JAVASCRIPT

1. Javascript is a computer language that may be used to create website scripts.

2. Javascript is a scripting language that can only be used in browsers.

3. It's primarily used on the client's end.

4. Javascript has the ability to add HTML and manipulate the DOM.

5. Javascript can run in any browser engine, such as Safari's JS core and Firefox's Spidermonkey.

6. In frontend development, Javascript is used.

7. RamdaJS, TypedJS, and other javascript frameworks are examples.

8. It's a newer version of ECMA script that makes use of Chrome's C++-based V8 engine.

nodejs

Node JS

1. NodeJS is a runtime environment for Javascript.

2. With the help of NodeJS, we can run Javascript outside of the browser.

3. It's primarily utilised on the server.

4. Nodejs does not support the addition of HTML tags.

5. Node's Javascript engine is called V8. js that parses Javascript and executes it.

6. In server-side development, Nodejs is employed.

7. Lodash, express, and other Nodejs modules are examples. These modules will be downloaded through npm.

8. C, C++, and Javascript are used to create Nodejs.

what is javascript

More about JavaScript:

JavaScript is a renowned programming language that is used for developing dynamic and interactive web pages. It enables the implementation of multifaceted functionalities on web pages.

It is an explicit open-source, lightweight, and cross-platform development language that is leveraged to build web apps.

ES2015

JavaScript is used to develop games, animated 2D & 3D graphics, and inclusive database-driven apps.

It is leveraged for client-side activities for web apps, such as attribute validation or refreshing the page in a set interval, or offering dynamic alterations in web pages without page refreshing.

JavaScript can be operated on any engine, comprising Spider Monkey, V8, and JavaScript Core.

It is commonly utilized on the client-side server.

It is better used to develop network-centric apps.

It operates on Chrome’s V8 engine, which is coded in C++ language.

JavaScript frameworks include TypedJS and RamdaJS.

Popular companies using JavaScript include Google, Microsoft, Shopify, Udacity, Uber, SendGrid, Groupon, Facebook, Okta, eBay, and Instacart.

All the JavaScript projects are not significant to the Node JS community.

JavaScript lacks multithreading and multiprocessor abilities.

Its key purpose is to develop complex interactive sites and games and to link servers to web applications.

Flow control in JavaScript is how your computer operates and runs code right from top to bottom.

JavaScript frameworks include Angular, React, Vue. JS, Ember. JS, Meteor, Mithril, Node. JS, Polymer, Aurelia, and Backbone.js.

The JavaScript runtime environment offers access to in-built libraries that are accessible to a program so that it can engage with the exterior space and make the code workable.

External libraries enhance productivity and resource consumption. The JavaScript Ecosystem is massive, and we can utilize it to save time and effort.

More about NodeJs:

Node.js is a precise open-source and cross-platform JavaScript that aids real time network app development. It is event-driven and non-blocking (asynchronous) I/O for building scalable server side JavaScript apps.

It is a precise cross-platform and open-source JavaScript runtime environment that enables JavaScript to be operated on the server.

js v18

Node.js can be leveraged to develop both web apps and native applications.

It is leveraged for accessing non-blocking operations such as creating a shell script or accessing any hardware-specific data, or operating backend jobs.

Node JS is merely backed by the V8 engine, which Google Chrome applies. JavaScript programs written with Node JS will always operate in the V8 engine.

It is commonly utilized on the server-side.

It is better used for data-intensive real-time apps that operate on multiple platforms.

It leverages C, C++ & JavaScript.

Lodash and express are instances of Nodejs modules. These modules are imported right from npm.

Popular companies using Node JS include Netflix, NASA, Walmart, PayPal, LinkedIn, Medium, and Trello.

All Node JS projects characterize and represent the JavaScript community.

Node.js has to deal with a lot of code alterations because of unstable API.

Its key purpose is to enable conventional websites and backend API services. It comes with real-time and push-based architecture.

Flow control in Node.js enables individual statements and instructions of an imperative program that is executed.

Node.js frameworks include MVC, Full-Stack MVC, and REST API frameworks.

Node. js is a cross-platform JavaScript runtime environment for apps and servers.

Node.js productivity and resource consumption can be boosted by front-end tooling, use of SSL/TLS and HTTP/2, caching, and optimizing data handling techniques.
