What is web development?

The process of creating websites and operations for the Internet or an intranet on a private network is known as web development. Web inventors produce the law that governs a website's style, layout, and interactivity. They also provide the site with functionality and aesthetic appeal.

Web development can be divided into three categories, or layers: database technology, frontend, and backend. Client-side scripting, sometimes referred to as front-end development, includes every aspect of a website that the user interacts with directly. The front end powers elements such as menus, contact forms, typeface, colors, and layout.

The world of server-side scripting, or backend development, is all about the background work. The front end notifies the backend when you act on a website, such as by filling out a form and clicking "submit." In response, the backend sends the front the pertinent data, such as the code required to show a message like "Thank you for completing this form."

Technology related to databases makes up the third layer. All of the material and files required for a website to operate are contained in the database, which arranges and stores the data to make it simple to access, manage, modify, and save.

In their daily jobs, web developers employ a variety of tools and technologies, but mostly languages, libraries, and frameworks.

Languages

The fundamental building blocks of the Internet are languages, which are used to develop software, apps, and web pages. Languages come in a wide variety, each with a distinct purpose.

A programming language is a set of commands or instructions that tell the computer how to carry out specific tasks. These programming languages are used by web inventors to produce the law that drives software, apps, and websites. Some of the more well-liked programming languages are Python, C, PHP, Ruby, and Java.

Markup languages

it is used to provide formatting specifications for text files, such as whether a specific sentence should appear bold on a web browser. The most widely used languages are XML and HTML. Style sheet languages are used to determine the style of documents that are written in markup languages. Thus, you may use style sheet language to add colors, alter the font, and add backdrops and borders to a plain HTML document. CSS is the most widely used stylesheet language.

Database languages are used to create and manage databases. The standard language for accessing and manipulating relational databases is SQL.

Libraries and frameworks

Libraries and frameworks are essentially collections of prewritten code. A library holds a collection of helpful code shortcuts; developers can utilize a prewritten, streamlined version from a relevant JavaScript library, like jQuery, rather than creating, say, ten lines of code in JavaScript. With prebuilt tools and components, frameworks provide developers with a set structure to work from, allowing them to write code more quickly.

Website speed

The percentage of visitors to a website that departs after viewing just one page or making their first visit is known as the bounce rate. One survey found that a little 2-second lag in a website's loading speed might cause a startling 103% rise in bounce rate. When creating a layout and other components for clients, web designers should always keep image optimization and compression in consideration.
