JavaScript or JS is a high-level programming language, developed by Brendan Eich of Ecma International thus also known as ECMAScript in 1995 and is considered as one of the core technologies (others being HTML and CSS) essential for the World Wide Web. This language helps in making web pages interactive and dynamic which makes it essential addition among web applications. Nowadays, almost every website and web applications use JavaScript and almost every web browser has a dedicated JavaScript engine embedded in them. Though, initially intended for the purpose for improving web applications its vast properties were explored and then, later on, people recognised if we could embed it into host software then it could be used for many purposes server-side programming in web servers, databases, in word processors etc. and in runtime environment which let’s JavaScript to script mobile and web applications and many more. JavaScript does have its own I/O, graphics, storage etc. that is why it relies on the environment in which it is embedded into.

JavaScript或JS是一种高级编程语言，由Ecma International的Brendan Eich开发，因此在1995年也称为ECMAScript，并且被认为是万维网必不可少的核心技术之一(其他是HTML和CSS)。 这种语言有助于使网页具有交互性和动态性，这使其成为Web应用程序中必不可少的功能。 如今，几乎每个网站和Web应用程序都使用JavaScript，并且几乎每个Web浏览器中都嵌入了专用JavaScript引擎。 虽然最初是出于改善Web应用程序的目的而进行探索的，但后来人们意识到，如果我们可以将其嵌入到主机软件中，则可以将其用于Web服务器，数据库，在文字处理器等中以及在运行时环境中，我们可以使用JavaScript编写脚本来编写移动和Web应用程序等。 JavaScript确实具有自己的I / O，图形，存储等，这就是为什么JavaScript依赖于其嵌入的环境。
