What is web development – The Essential Guide to Web Development

Web development is the process of creating a website or piece of software from scratch. Developers work on the code for these websites and applications, making them as functional and user-friendly as possible.

To become a web developer, you need to read this guide and do the exercises.

This article is about how web development works and what it takes to become a professional web developer. It can seem a bit complicated at first, but we’ve made it as simple as possible so you can understand.

In this guide, we’ll talk about web development in detail, and then show you the essential skills you’ll need to start working in the web development industry. If you decide web development is something you’d like to try, the next step is to start learning the skills you need, which you can do in this free coding course for beginners.

Types of web development

Web development can be broken down into three parts: designing and creating the graphics and user interfaces on the client side, writing code that runs on the server side, and using databases to store information.

These are the different parts of your skin. The top layer is called the epidermis. The next layer down is the dermis. Beneath that is the subcutaneous layer, and finally the muscle and bone layer.

1. Frontend
   Client-side scripting is what the user sees and interacts with on the website. This includes things like the layout, fonts, colours, menus, and contact forms.
2. Backend
   Backend development is all about what happens on the computer that the website is hosted on. This includes programming code that runs on the server and all the procedures and processes that go along with running a website. The backend is part of a website that the user doesn’t see. It is responsible for storing and organizing data, and ensuring that everything on the client side runs smoothly. It does this by communicating with the front end. Whenever you interact with the internet, your browser sends a request to the server. The server responds with code that the browser can understand, which results in the page you see. Frontend and backend are different parts of a computer system. The front end is part of the computer that you see and use, like the screen and keyboard. The backend is part of the computer that does the work, like the processor and storage.
3. Database technology
   A database is a collection of information that websites use to keep track of their files and content. Websites use a database to store all the information they need, and most use a type of database management system (DBMS) to keep track of the information. The front end, back end, and database technologies all help create and run a website or application. These three layers are the foundation of web development.

What does a web developer do?
A web developer creates and maintains websites. They can work for an organization or on their own, and the tasks they perform will depend on the type of website they’re working on.

There are three types of web developers: frontend, backend, and full-stack. A full-stack developer knows how to do both the design and programming for both the frontend and back end of a website.

Web developers work together with other people to create a product that meets the needs of both the client and the customer or end user. They look at the vision for the website and work together with other people to make sure it looks and works the way the client wants it to.

Web developers are experts at troubleshooting and fixing problems on websites and systems. They keep things running smoothly by coming up with solutions to problems.

Different developers use different programming languages for different reasons. Some developers specialize in working with particular programming languages, while others use different languages for different tasks depending on their job. For example, some developers use programming languages like Python to develop web applications, while others use languages like HTML and CSS to design the look and feel of websites.

Programming languages, libraries, and frameworks

Web developers use languages, libraries, and frameworks to create websites and apps. These tools can help them create the code necessary to make their projects work.

Languages are the instructions that programmers use to create websites, apps, and software. There are many different kinds of languages, including programming languages, markup languages, style sheet languages, and database languages. Programming languages are used to write source code. High-level languages use logical words and symbols, making them easy for humans to read and understand. High-level languages can be compiled or interpreted. C++ and Java, for instance, are compiled high-level languages. They are first saved in a text-based format that is comprehensible for human programmers but not for computers. In order for the computer to run the source code, it needs to be converted to a low-level language; i.e. machine code. Compiled languages tend to be used to create software applications. Low-level languages are those that can be directly recognized by and executed on computer hardware; they don’t need to be interpreted or translated. Machine language and assembly language are some common examples of low-level languages. Interpreted languages like Perl and PHP do not need to be compiled. Instead, source code written in these languages can be run through an interpreter—a program that reads and executes code. Interpreted languages are generally used for running scripts, such as those used to generate content for dynamic websites. Databases are used to store large amounts of information. For example, the Spotify music app uses databases to store music files and data about the user’s listening preferences. Social media apps like Instagram also use databases to store user profile information. Whenever a user updates their profile in any way, the app updates their database too. Databases are not written in the same language that apps are, so it’s important to use a language that the database can understand – like SQL.

Other web development tools include a text editor, such as Atom, Sublime or Visual Studio Code, a web browser, such as Chrome or Firefox, and an extremely important tool: Git. Git is a version control system that helps developers keep track of changes to their code.

How to become a web developer

Do you want to focus on back-end development? In that case, you may want to consider a course that teaches you the Python language. This course will also teach you the basics of web development, such as HTML/CSS, JavaScript, and AJAX. Alternatively, if you want to focus on front-end development, you may find a course that teaches you the HTML, CSS, and JavaScript languages. However, you won’t learn about back-end development in this pathway. Do you want to learn in a self-paced manner? Do you want to focus on a specific language or framework? Do you want to learn web development in total? In that case, you may want to consider a course that teaches you both frontend and backend development. This course will also teach you about frameworks, tools, and common terminology. In that case, you may want to consider a course that teaches you that language or framework exclusively. This way, you will be able to learn everything you need to know about the language or framework, without any other conflicting topics.
