differences between backend and frontend in application development

As they know, an application or even a site is divided into two parts. One section is Backend, and the other is Frontend.

The front end is the part of  the web or application  that the user will see. In other words, we can say that Frontend is the appearance of the program or site that is visible to the user.

The back end of  a site or application is the basis that the developer  deals with, and the user will never see it. In other words, we can say that Backend is behind the scenes of a program or site. If we want to give an example for Backend, we will use the Internet form. When you fill out and enter your information in online forms or create user accounts and enter your data and information, you only see the page the programmers want you to see, which is Frontend. But at this time, the data and information you enter are being transferred to the database, which is related to the Backend, and the user cannot see it.

In general, for example, we can say that the central part that causes the activity of software or even a site is Backend. All the codes related to creating the main base of a site application and increasing speed, security, and performance are listed in the Backend section. The user can't see the Backend, and the user can only see  the Frontend section of the site or software.

What does the Frontend programmer do?

The job of a Frontend programmer is to create the look of an app or site. There are some things to keep in mind when creating a Frontend. To be able to  design the appearance of applications and websites, the Frontend programmer must have a complete mastery of graphic knowledge to do them efficiently. On the other hand, after designing the elements, to arrange the ingredients in the right places of the application, the program must have mastered programming knowledge. The languages ​​used to create and design appearance or Frontend programming are CSS in web design and development and XML language in  application design and development.

What does a Backend programmer do?

The main task of designing and developing web and application ( in Czech:  navrhování a vývoj webu an aplikací  ) is the responsibility of the Backend programmer. In this case, the task of building the base and the main part of a site and application will be done by the Backend programmer. Without a Backend programmer, there will be virtually no applications and sites. It is the Backend programmer who can create an application and a site.

The languages ​​used for this program are as follows:

To program and create Frontend, which is the visible part of an application or site for the user, you must use its programming languages. HTML, CSS, and JavaScript are some languages ​​that can be used to design and create a visible part. These three languages ​​are used to  design and build a visible part of an application : Frontend.

- HTML:

Contrary to popular belief, HTML is not a programming language but a markup language that can be considered the core and body of web pages. HTML is not a programming language but a markup language, meaning that all code inserted using markup languages ​​is like a text file with tags separating their various components. These types of languages ​​are used to design sites.

- CSS:

This type of language is not a programming language but a markup language used in the design of Frontend sites. CSS stands for Cascading Style Sheets, which means styling web pages. Using this language, you can use captions, images, videos, text, etc., to style web pages. In other words, we can say that in designing the site frontend, we place different types of elements on the site using a markup language, and then we style them using CSS styling language. Using this language, site designers can  design the site's appearance without any creative restrictions.

- Javascript:

This language is one of the languages ​​that is user-friendly. Using this language, the site designer in Frontend design can animate pages created using HTML and CSS languages. In other words, it can be said that by using this programming language, the created pages can be animated and made dynamic. For example, if we want to say, we can enter the command to perform actions using this language. If there is a button in the forms to confirm and send the entered data, this language transfers data.

Skills required for Frontend programming

As we said, Frontend programming refers to all the code inserted to change the site's appearance or the part visible to the user. For a Frontend programmer to easily  create the look of a site or application, they must have some skills.

- Learn HTML, CSS, and JavaScript programming languages

One of the necessary skills for a programmer to become a Frontend and  design a Frontend site and application  is to learn and master the unique programming languages. The first step is to be able to learn Frontend-specific programming languages ​​professionally. Of course, it should be noted that Frontend programming is much easier than programming in other areas.

- Javascript libraries and frameworks

Due to the advancement of technology and  the increase in the number of designers and developers of applications and sites, different types of libraries are created every day to do this. That's why we must do particular frameworks and libraries for it. Javascript frameworks include Angular and Vu.js.

- Familiarity with the principles of responsive design

The user interface on sites or applications should be responsive and user-friendly. The responsiveness of the site and the application means that it can respond appropriately if there is a problem.

- Learning design and graphic software such as Photoshop

It is worth mentioning thata to  design the appearance of the site and application, you must have mastered some graphic software such as Photoshop. Using this graphic software, the necessary drawings and designs for the appearance of the site and the app will be done in addition to the Photoshop graphic software, other software such as Figma, Adobe xd, etc.

- Creativity in designs

Since the designer and programmer Frontend is responsible for designing the appearance of the site and application, he must be creative. Creativity is essential in drawings and designs, and that the procedures done for the formation of the app and the site must be creative and different. On the other hand, the designer must be creative and tasteful to design user-friendly designs.

How Much Money Does this Programmer Make?

The average salary of a Frontend programmer in the world is between $ 65,000 and $ 110,000.

Here are some important Frontend jobs:

As we mentioned in this article, an application or site is created from two parts, and there are some differences between Frontend and Backend.  To create and develop different applications on any platform and site, we must consider the design and development of two essential parts: Backend and Frontend. The front end is the part of the app or site in front of the user, and the back end is the part of the app and site that is the central part and is related to creating the foundation.
