5. HTML
 Hypertext Markup Language (HTML) is the
standard markup language for creating web pages and web
applications.
 HTML is a Markup Language. It uses Markup tags to describe
Web pages.
 The future of HTML is XML (eXtended Markup Language)

 Alongside HTML and CSS, JavaScript is one of the three
core technologies of the World Wide Web.
 JavaScript enables interactive web pages and thus is an
essential part of web applications.

8. Why JS?
 JavaScript enhances web pages with dynamic and interactive
features.
 JavaScript runs in client software.
 JavaScript can react to events.
 JavaScript can read/write/modify HTML elements.

9. React JS
 React js is a JavaScript library for building user interfaces. It
is maintained by Facebook and a community of individual
developers and companies.
 React can be used as a base in the development of single-
page or mobile applications.
 Complex React applications usually require the use of
additional libraries for state management, routing, and
interaction with an API.

10. Why React JS?
 Virtual DOM – React js use the concept of virtual DOM which
helps in the performance.
 Unidirectional Data Flow – Compared to the two way
binding. React js use the concept of unidirectional data flow
which improve the overall performance.
 UI Components – Reusable and interactive components.
 Coding is simpler because of JSX.

11. SQL
 Standard Query Language (SQL) is a standard language for
storing, manipulating and retrieving data in databases.
 SQL lets you access and manipulate databases

12. Node JS
 Node.js is an open-source, cross-platform JavaScript run-
time environment that executes JavaScript code outside of a
browser.
 Node.js lets developers use JavaScript to write Command
Line tools and for server-side scripting
