Front End vs. Back End: What’s the Difference?

Front End vs. Back End: What’s the Difference?

Frontend is the part of the application that is responsible for user interaction, and the Backend is responsible for the logic of the application. Simply put: the Frontend is the “visible” part of the application, and the back-end development is responsible for storing and processing data. So anything that is not visible at first glance – the page interface, text layout, menu or graphics – these results are drawn and displayed by the Frontend from the Backend, and we finally see them on the screen of a monitor, smartphone or tablet.

It is said that an IT front-end development professional needs to know the three most important programming languages: HTML, CSS, and JavaScript. Each of them probably serves a different function when programming websites and applications.

HTML is responsible for the structure of the application, which allows us to create the appropriate layout of the elements on the website. CSS provides images, and JavaScript adds logic to our application for user interaction. Only a combination of all three allows us to create a fully functional internet application.

What about the frontend tech stack? Does it change or update frequently?

The front-end technology stack is changing very dynamically, which discourages many young programmers from choosing this branch of programming. This was influenced by the great popularity of JavaScript, which is reflected in the constant creation of new libraries and frameworks. However, it should be remembered that learning at least one technology makes it much easier to master others based on the same programming language.

What does Frontend Developer do on a daily basis?

Frontend Developer is concerned with creating a GUI for an application and connecting it to server applications. This means that a good frontend developer must be able to put all the pieces of an application together to create a clean and intuitive interface.

Soft skills are a very important and often overlooked element in this position. Frontend integrates all parts of the application, so the work of the frontend forces us to often interact not only with our own, but also with other teams.

Then what should a frontend developer be able to do? Are there grounds without which it would be impossible to work in this position?

Basic knowledge of HTML, CSS and JavaScript is a must – you cannot work without them. Currently, the vast majority of applications are not created using pure JavaScript, but libraries and frameworks are created on its basis, so you will need to study at least one of them. Currently, the most popular web technologies are Angular, React.js, and Vue.js. Another extremely important tool required in the work of every programmer is GIT, that is, a version control system.
