What is a web developer?

The job of web developer appeared, as its name suggests, with the birth of the web as we know it. That is to say the setting of pages in HTML mixing text, links, images, addressable via a URL.

What is web development?

Web development generally refers to the tasks associated with the development of websites intended to be hosted via an intranet or the internet. The web development process includes, amongst other things; website design, web content development, client or server-side scripting and network security configuration.

Web development is the coding or programming that makes a website work, depending on the owner’s requirements. It mainly deals with the non-conceptual aspect of website creation, which includes coding and writing markup.

Web development ranges from creating plain text pages to complex web applications.

What is the function of a web developer?

A web developer, or programmer, is someone who takes a web project, which has been carefully thought through by a client or design team, and in consequence, turns it into a website. They do this by writing lines of complicated code. To write them, they use different languages with specificity and usefulness applicable to each of them.

Web developers have a somewhat difficult job, in that, they have to take a language we understand, like English, and translate it into a language that a computer understands, like PHP or HTML.

As you can imagine, it takes much time and effort to learn different programming languages and their uses. As well as this, languages change and develop over time.

The 3 types of web developers

Front-end developers take care of the part of a website that people see and interact with.

Back-end developers are responsible for the code in the background. This code will be used to control how a website will load and run.

Full-stack developers effectively undertake a little bit of everything.

The terms “front-end” and “back-end” are used in the programming profession to describe the layers of a website.

Front-end web development

A front-end developer will take charge of the website design and write the code necessary to implement it on the web. Front-end developers must master at least three programming languages: HTML, CSS and JavaScript. They have responsibilities in natural referencing (SEO), graphic design and editing of site images and photos. But also for the different tests (usability and accessibility) as well as the performance of the website and its compatibility with the different browsers and display format (mobile, desktop). In other words “responsive design”.

The different languages used in front-end web development

HTML lets you embed content into a website while dividing it into titles, paragraphs, and tables. It is an essential language. It tells the website what content to display and, to some extent, how to display it.
Commands such as “link”, “image” or “video” tell your browser what to display, where to get the content, and how to display it.

CSS is used in conjunction with HTML. While HTML tells the web page what content to display, CSS tells the web page how to display content; it’s a “style” language. It will allow the change of colours, fonts, as well as the positioning of the elements and change of text size.

JavaScript is all about making your website responsive, interactive, and engaging for your visitors. A JavaScript developer will work on snippets of JavaScript code, which will often be incorporated into the HTML source code of a website. Although it has always been a front-end language, JavaScript is also becoming more and more popular for mainstream development.

Back-end web development

While front-end developers are responsible for client-side programming, back-end developers must take care of the server-side.

This means that they have to create the code and the programs that feed the website server, the databases and all the applications that the website contains. They use a wide range of different server-side languages to build complicated programs.

Among the most used languages are PHP, Python, Java and Ruby, whilst SQL language is commonly used to manage and analyze data in website databases. We are only going to cover PHP code in this article.

The speed of a website being a major consideration when it comes to search engine optimization (SEO), it is an important factor when developing the back-end.

The different languages used in back-end web development.

PHP has dominated the definitions of what web development is. Known as the language of the internet, it is currently used in one form or another on over 80% of existing websites. PHP is very popular with developers, especially on websites built on platforms like WordPress. PHP plays a particularly important role in WordPress development.

This language allows you to do things such as create dialogue boxes that open on a screen in response to a user’s actions. But also for chatbots responding to defined user behaviour with corresponding messages, or an animation that occurs when a user scrolls past a certain point on a page. Effectively, all of the dynamic website functions that should occur on the screen without the user having to reload a site manually.

Those languages will make it possible to achieve and ensure scalability and availability of the network as well as database management, their backups, their transformations and their cybersecurity.

What is the difference between web design and web development?

Web design and web development are two different things, but of course, it depends on how you define ‘design’ and ‘development’. These professions are different, and they have the following roles:

The web designer

The web designer is the person who is responsible for creating the concept of the website. He can decide that the site must have a particular colour, a certain content and specific pages. He is an expert in computer graphics and has the technical skills necessary to create logos and graphics. It tells the developer where these items should be placed on the web page. However, he does not participate in the construction of the website or the underlying code.

The web developer

The web developer takes the designer’s concepts and creates the code. He uses the different technologies and resources previously seen, to transform and design an idea into a website, and make it available to people like you.
