What Does a Front-End Developer Do?

As discussed, these developers typically deal with the visual outlook of the website to enhance the user experience. After going through the significant differentiating points between front-end and back-end development, you have understood the general roles of front-end developers. Now, let’s discuss the roles and skill set you need to start a career as a UI/UX developer.

Front-End Developer Job Duties

Young developers determined to excel in the website creation field can start their careers as front-end experts. When taking the role of such a developer, you will need to fulfill the following roles and responsibilities:

  • Developing User Interfaces: As a front-end developer, you design and implement UI/UX using front-end languages such as HTML and JavaScript. Moreover, you should also ensure that the visual aesthetics align with design specifications and brand guidelines.
  • Creating Responsive Design: When comparing front-end developers vs. back-end developers, the first one is responsible for creating interactive layouts. Doings so they need to make the websites work seamlessly across various devices and screen sizes.
  • Performance Optimization: These developers also need to optimize the performance of web applications for speed and efficiency. In addition, their role is to minimize load times by optimizing image quality.
  • Implementing Animation and Visual Effects: Front-end developers should also be able to generate animations and transitions to enhance user experience. Other than that, they need to have the knowledge to use CSS animations or JavaScript libraries for advanced animations.

Front-End Languages

While discussing front-end and back-end developers, the first one needs to have command of the following languages. Let’s discuss each of these languages briefly to help you understand their role in front-end development:


Using this programming language, front-end developers create the basic structure and content of a web page. Furthermore, this language defines elements such as headings, images, and other content types. Overall, we can say that HTML provides the basic web framework that is enhanced and styled using CSS and JavaScript.

2. CSS

UI designers use this language to optimize the visual styling and layout of a web page. Other than that, it enhances the HTML structure by applying styles like colors, fonts, and margins. Also, CSS enables responsive design to let web pages adapt to various screen sizes and devices.

3. JavaScript

With the help of this language, front-end developers add interactivity and dynamic behavior to websites. Upon manipulating DOM, JavaScript enables real-time updates, animations, and user interaction without reloading the page.

4. Sass

The capabilities of the standard CSS are enhanced by this advanced language with features such as variables and nested rules. When comparing front-end vs. back-end developers, the first one utilizes this language to write more maintainable and reusable stylesheets.

Front-End Frameworks

Front-end developers don’t have to start from scratch to create responsive websites. Young UI designers can make use of multiple frameworks to save the time and effort required to build responsive web pages. The following JavaScript and other language frameworks provide users with a pre-written library of codes to help them automate basic website-building tasks:

  • React
  • Angular
  • Vue.js
  • Svelte
  • Backbone.js
  • Foundation
  • Bootstrap
  • Semantic UI
  • Bulma
  • Ember.js

What Do Back-End Developers Do?

Continuing our discussion about front-end vs. back-end development, we can say that the latter focuses majorly on the website servers. The role of the back-end developers in website maintenance and performance is much larger than the UI designers. So, let’s dig deep into the responsibilities and skill sets of the developers to inspire you to become a full-stack developer.

Back-End Developer Job Duties

When beginning your career as a back-end developer, you should be skilled enough to handle these primary responsibilities. Go through the points explained below to fully understand the job role of a professional back-end developer:

  • Server-Side Development: While comparing front-end developer vs. back-end, the latter is responsible for developing, maintaining, and optimizing server-side applications. In addition, they play a significant role in implementing business logic and algorithms for various functionalities.
  • Database Management: Back-end developers should also know how to design and manage databases using SQL and NoSQL technologies. Moreover, they need to have an understanding of writing efficient database queries and optimizing website performance.
  • API Development and Integration: These experienced developers need to develop and maintain APIs for communication between front-end and back-end systems. Also, their responsibilities include integrating third-party services and APIs as needed.
  • Code Maintenance: After comparing front-end vs. back-end developers, we came to know that the latter usually maintain and refactor existing code to improve website performance.

Back-End Languages

While carrying out the back-end development, the use of languages depends on the website component you are building. Now, analyze these back-end languages individually to comprehend their role.

1. Python

With the help of this simple language, back-end developers can carry out the rapid development and prototyping tasks. While building web applications, you can utilize the frameworks written in this language, including Django and Flask.

2. Java

Back-end developers utilize this language to build large-scale web applications. Moreover, the platform-independent nature of Java makes sure that these apps can run on any system.

3. Ruby

After comparing front-end and back-end development, you will know the importance of this language. As this language focuses on simplicity, startups mostly use it for website development.

4. PHP

Using this server-side scripting language, full-stack developers can build and manage complex websites. Other than that, this language can be embedded within HTML to integrate seamlessly with various database systems.

Back-End Frameworks

Young professionals starting their careers in web development can use pre-built frameworks to make their job easier. With these already-written code lines, back-end developers will be able to save time while building complex web pages. Analyze this comprehensive list of back-end frameworks to select the best one for your web development process:

Q1: What is the primary difference between front-end and back-end development?

Front-end development focuses on the visual and interactive aspects of a website or application that users interact with directly. This includes HTML, CSS, and JavaScript. Back-end development deals with server-side logic, databases, and application functionality, which users do not see. It involves languages like Python, Ruby, Java, and database management.

Q2: How do front-end and back-end developers collaborate?

Front-end and back-end developers collaborate by working together on the API endpoints that connect the user interface with the server-side logic.
