Background: The Evolution of Node.js and JavaScript

programming code

To understand the difference between Node.js and JavaScript, it’s essential to explore their origins and how they have evolved over time.

JavaScript, created by Brendan Eich in 1995, is a lightweight, versatile, and open-source scripting language. Initially, it was designed to add interactivity to HTML pages. However, over the years, JavaScript has evolved into a powerful language that can run on multiple platforms, including web browsers, servers, and even mobile devices. It supports features like cross-compilation, classes, and interfaces, making it a popular choice for front-end development.

On the other hand, Node.js was created by Ryan Dahl in 2009 as an open-source JavaScript runtime environment. It allows developers to execute JavaScript code outside of the browser, opening up new possibilities for server-side development. Node.js utilizes the V8 engine, which is also used by Google Chrome, to run JavaScript code efficiently. With the support of Node.js, developers can build scalable and high-performance web applications that are capable of handling a large number of concurrent requests.

Now that we have a brief background, let’s explore the unique features and use cases of Node.js and JavaScript in more detail.
