The front-end is the component of the website that runs on browsers like PC and mobile and displays web pages for people to peruse. Most backend developers focus on the logic that goes into creating functional apps. To execute a project together, the front and back ends must work together. So, what exactly is the front end? What exactly is the backend?

Frontend Development

The interface of the website that is prepared for the users. With the advancement of Internet technology, HTML5, CSS3, the use of a front-end framework, cross-platform responsive web design can adjust to various screen resolutions, perfect motion design, and provide users with a very good user experience.

Front-end technology is separated into two categories: front-end design and front-end development. Front-end design is the visual design of a website, whereas front-end development is the execution of a website's front-end code, which includes fundamental HTML and CSS, JavaScript/ajax, and the newest sophisticated versions HTML5, CSS3, and SVG, among others.

HTML (HyperText Markup Language ) , CSS (Cascading Style Sheets ) and JavaScript are the most fundamental and important abilities in front-end development. When the page is built up in front-end development, HTML describes the elements, CSS arranges the displayed elements, and then JavaScript is used to produce the necessary impact and interaction. Although it appears to be easy on the surface, there is no shortage of things to learn. Before you begin working, you should clarify and comprehend these principles so that you can be useful during the development process.

• HTML
  The most widely utilised language on our web sites. It has gone through multiple phases of development and has reached version 5.0. It has been generally upgraded to XHTML, XHTML refers to the Extensible HyperText Markup Language (EXtensible HyperText Markup Language), XHTML became a W3C standard on January 26, 2000, and is a tighter and purer HTML code, thanks to the rules and specifications developed by W3C. XHTML's purpose is to replace HTML. XHTML is a W3C standard that is virtually identical to HTML 4.01. XHTML is HTML redefined as an XML application. The World Wide Web Consortium defines XHTML as the most recent version of HTML. XHTML is supported by all modern browsers.
• CSS
  Cascading Style Sheet (Cascading Style Sheet), generally known as "CSS", is a type of style sheet that is used to design web pages. This is a style if you want the link text to be blue when not clicked and red and underlined when the mouse is hover it. The display attributes of each mark in HTML may be controlled universally by using a style sheet. Cascading style sheets allow users to have greater control over the design of web pages. You may increase the ability to precisely determine the placement and look of web page elements, as well as create special effects, by using Cascading Style Sheets.
• JavaScript
  It is a case-sensitive client-side scripting language of the object-oriented dynamic variety, derived from Netscape's LiveScript which used to improve browsing experience. The server needs to validate the data at the moment. Because the network bandwidth was so sluggish, barely 28.8kbps, the verification stage took much too long. As a result, Netscape's Navigator browser joined Javascript to provide rudimentary data validation features.

Backend Development

The majority of backend developers construct the real logic underlying the programme they are working on. Front-end developers create the user interface, while back-end developers construct the code that allows it to function. The code that makes the button operate is written by the back-end developer, who specifies what data to extract from the database and deliver back to the front-end. Backend developers may also be significantly involved in system design, selecting how to structure the system's logic so that it can be properly maintained and run.

May be involved in the development of frameworks or system designs to make programming easier. Backend developers devote more effort on algorithm implementation and issue solving than frontend devs. Front-end development is frequently more concerned with building the user interface and associated elements than with implementing the underlying business logic that makes the application operate.

Front-end developers must be familiar with a variety of tools for building user interfaces, but back-end developers frequently employ an entirely separate set of tools and abilities to execute their duties efficiently. SQL and database knowledge are crucial skills for backend developers. The majority of backend systems require a connection to a database that holds application data.

Backend developers often produce, read, and analyse data from databases or other data sources, therefore SQL knowledge may be quite useful. Backend engineers must be proficient in server-side languages for the technology stack they are working with, at least for web development.

Backend developers should learn more about application architecture because they are often responsible for the architecture and internal design of the programme. A skilled backend developer should understand how to use numerous frameworks and libraries, how to integrate them into an application, and how to arrange the code and business logic such that the system is easy to maintain.

The user-visible interface is the web page development, the front-end work content is to create the renderings of the art design into a web page that the browser can run, and collaborate with the back-end to display data and interact with the web page. Aspects of work content; the back-end refers to items that are not apparent to users, such as data interaction with front-end engineers and website data storage and reading. In comparison, the back-end has more logic code than the front-end. The conclusion takes into account the implementation of the underlying business logic, the platform's stability and performance, and so on.
