What is JavaScript?

JavaScript is a programming language that is commonly used to add interactivity and dynamic functionality to web pages. It is a client-side scripting language, which means that it is executed on the user's computer within their web browser rather than on a web server. JavaScript can be used to manipulate HTML elements and CSS styles, as well as to interact with web APIs and to create animations, games, and other complex web applications.

• JavaScript was first created by Brendan Eich in 1995, and has since become one of the most widely used programming languages in the world. 
• It is supported by all modern web browsers and is used extensively in front-end web development, as well as in server-side applications using frameworks like Node.js.

What is CSS?

• CSS stands for Cascading Style Sheets, and it is a language used to style and format HTML documents. 
• CSS is used to control the presentation of web pages, including layout, colors, fonts, and other visual elements. 
• By separating the presentation layer from the content layer (which is defined using HTML), CSS allows web designers to create consistent and visually appealing designs across multiple web pages, while also making it easier to update the design of a website without changing the underlying content. 
• CSS works by specifying rules that apply to different HTML elements, allowing designers to control how those elements appear on the page.

what is HTML?

HTML stands for Hypertext Markup Language. It is a markup language used to create and design web pages. HTML is the standard language used for creating documents that are meant to be displayed on the World Wide Web. It uses a set of markup tags and attributes to define the structure and content of a web page.

HTML allows you to define headings, paragraphs, lists, tables, and other page elements, and also provides a way to include images, videos, and other multimedia content on a web page. HTML is a key component in web development, as it provides the basic building blocks for creating visually appealing and interactive web pages.
