Surely you have repeatedly wondered who a front-end developer is, what his tasks are, what he does, and what is front-end development technologies in general. Let’s take a closer look at what “front-end” means, what is its difference from “back-end” and what skills you need to have in order to become a sought-after front-end developer.

What is Frontend?

A frontend is a public part of web applications (websites) with which the user can interact and contact directly. Frontend Development Services include displaying functional tasks, a user interface performed on the client-side and handling user requests. In fact, the frontend process is everything that the user sees when opening a web page.

FrontEnd Development

In turn, a web application is a client-server application, in which the client is mainly a browser, and a server is a web server. The logic of the web application is distributed between the server and the client, data storage is carried out mainly on the server, information is exchanged over the network. Simply put, this is what the user sees and what actions he performs every time he connects to the Internet and opens any browser.

Frontend development is the work of creating the public part of a web application, with which the user directly contacts, and functionality, which is usually performed on the client side. That is, the front-end developer is working to ensure that each button, icon, text and window on the site not only stands in its place, does not overlap each other and looks whole (this is a web layout), but also that they fulfill their intended purpose – performed some action (for example, for the “buy” button to open the cart, and “play” to start the playback of a movie or music).

In order to create a demanded and affordable product (web application), a front-end developer needs to interact with other programmers, designers, marketers, analysts and other specialists.

Front-end development components:

  1. HTML (HyperText Markup Language) in simple terms is a markup language for all elements and documents on a page, and their interaction in the structure of the page.
  2. CSS (Cascading Style Sheets) is a language for characterizing and styling the appearance of a document. With the help of CSS code, the browser understands exactly how to display the elements. CSS creates fonts, colors, determines the location of site blocks, and more. Also adapts the same document in different styles, displays the transmission on the screen or for reading by voice.
  3. JavaScript is a language designed to bring web pages to life. The task of JavaScript is to respond to user actions, handle keystrokes, cursor movements, and mouse clicks. JavaScript also allows you to enter messages, send requests to the server, and load data without reloading the page, and so on.
