Developments About Software

JavaScript is a high-level, interpreted programming language that conforms to the ECMAScript
specification.
JavaScript has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class
functions.

Alongside HTML and CSS, JavaScript is one of the core technologies of the World Wide Web. JavaScript
enables interactive web pages and is an essential part of web applications. The vast majority of
websites use it, and major web browsers have a dedicated JavaScript engine to execute it.

As a multi-paradigm language, JavaScript supports event-driven, functional, and imperative (including
object-oriented and prototype-based) programming styles. It has APIs for working with text, arrays,
dates, regular expressions, and the DOM, but the language itself does not include any I/O, such as
networking, storage, or graphics facilities. It relies upon the host environment in which it is embedded to
provide these features.

Initially only implemented client-side in web browsers, JavaScript engines are now embedded in many
other types of host software, including server-side in web servers and databases, and in non-web
programs such as word processors and PDF software, and in runtime environments that make JavaScript
available for writing mobile and desktop applications, including desktop widgets.

The terms Vanilla JavaScript and Vanilla JS refer to JavaScript not extended by any frameworks or
additional libraries. Scripts written in Vanilla JS are plain JavaScript code.

Although there are similarities between JavaScript and Java, including language name, syntax, and
respective standard libraries, the two languages are distinct and differ greatly in design.
