HTML

 HTML

HTML, or HyperText Markup Language, is the standard markup language for texts intended to be displayed in a web browser. It can be aided by technology like Cascading Style Sheets (CSS) and programming languages like JavaScript.

Web browsers accept HTML documents from a web server or local storage and convert them to multimedia web pages. HTML semantically explains the structure of a web page and initially provided signals for the look of the content.

The earliest publicly available definition of HTML was a document named "HTML Tags," which Tim Berners-Lee initially discussed on the Internet in late 1991. It explains the first, rather simplistic design of HTML, which consists of 18 components. SGMLguid, CERN's in-house Standard Generalized Markup Language (SGML)-based documentation format, had a considerable effect on these, with the exception of the hyperlink tag. Eleven of these components can still be seen in HTML 4.


Berners-Lee regarded HTML to be an SGML application. The Internet Engineering Task Force (IETF) formally defined it as such with the publication in mid-1993 of the first proposal for an HTML specification, the "Hypertext Markup Language (HTML)" Internet Draft by Berners-Lee and Dan Connolly, which included an SGML Document type definition to define the grammar. The proposal was only valid for six months, but it was important for recognizing the NCSA Mosaic browser's custom tag for embedding in-line pictures, demonstrating the IETF's principle of building standards on successful prototypes. Similarly, Dave Raggett's rival Internet-Draft, "HTML+ (Hypertext Markup Format)," published in late 1993, proposed standardized already-implemented elements like as tables and fill-in forms.

React

  React. React (also known as React.js or ReactJS) is a free and open-source front-end JavaScript toolkit for creating UI components-based user interfaces. Meta (previously Facebook) and a community of individual developers and corporations manage it. React may be used as a foundation for single-page or mobile apps. However, because React is primarily concerned with state management and presenting that information to the DOM, constructing React apps frequently necessitates the usage of extra frameworks for routing and client-side functionality. Jordan Walke, a Facebook software developer, designed React after releasing an early version named "FaxJS." XHP, a PHP HTML component package, impacted him. It was originally used in the Facebook News Feed in 2011, and then on Instagram in 2012. It was released as open source in May 2013 at JSConf US. React Native, which enables native Android, iOS, and UWP programming with React, was introduced in February 2015 at Facebook's React

JavaScript

  JavaScript.      JavaScript, abbreviated JS, is a computer language that, together with HTML and CSS, is one of the essential technologies of the World Wide Web. Over 97 percent of websites employ JavaScript on the client side to control web page behavior, with third-party libraries frequently used. To run the code on the user's device, all major web browsers include a specialized JavaScript engine.  JavaScript is an ECMAScript-compliant high-level, typically just-in-time compiled language. Dynamic typing, prototype-based object-orientation, and first-class functions are all included. It supports event-driven, functional, and imperative programming approaches and is multi-paradigm. It supports text, dates, regular expressions, standard data structures, and the Document Object Model via application programming interfaces (APIs) (DOM). The ECMAScript standard does not contain any input/output (I/O) capabilities like as networking, storage, or graphics. In reality, JavaScript APIs f

Python

  Python Python is a high-level general-purpose programming language that is interpreted. With the usage of considerable indentation, its design philosophy prioritizes code readability. Its language elements and object-oriented approach are intended to assist programmers in writing clear, logical code for small and large-scale projects. Python is garbage-collected and dynamically typed. It supports a variety of programming paradigms, including structured (especially procedural), object-oriented, and functional programming. Because of its extensive standard library, it is frequently referred to as a "batteries included" language. Guido van Rossum began developing Python as a replacement to the ABC programming language in the late 1980s, and it was originally released in 1991 as Python 0.9.0. Python 2.0 was launched in 2000 and included new capabilities such as list comprehensions and a garbage collection mechanism that detects cycles (in addition to reference counting). Python
