Front-end vs Back-end Developer: What Is The Difference?

Creating intuitive and interactive web and software applications is no longer a distant dream. The advancements in web development are here to stay and to help developers with building applications that know little to no boundaries. With a plethora of tools and technologies at their disposal, they can weave customer experiences that are tailored down to every detail. The industry is so vast today that it can get a little overwhelming for beginners in the industry to grasp complex terminologies well within time.

For any and every professional in the web development space, two terms are of utmost importance – front-end and back-end. When starting their journey to success, most aspirants find themselves disentangling the dilemma of front-end vs. back-end developer – what do these roles entail and how are they different from one another. Beginners must choose wisely as these terminologies lie at the very foundation of their careers. Your ultimate choice between front-end vs. back-end carves the path ahead in your web development journey.

If you are one such development enthusiast who is new to the industry, then this blog will serve to be the perfect guide. It will help you best understand these roles and their nuances. Let’s start with what these two types of development mean individually, then move on to exploring front-end and back-end languages, frameworks, and finally the key differences between them.

What Is Front-end Development?

In this method of programming, the developer has to focus more on the user experience aspect of the applications. In simple terms, it comprises writing precise codes that will effectively build the key website elements and features. The key aspects built on the back of coding will then be visible to the users on their screens in a collective manner. They are not just expected to be visually appealing but also equally functional, in the sense that they should guide the users when they are browsing through the website.

Front-end is also commonly referred to as the ‘client-side’ aspect of the application. Expert front-end coding is the best way to bring seamless navigation to users. The developers ideally leverage the UI/UX elements provided by the designer and then make them interactive and functional. They are also expected to work on elements like layout, infographics, images, animations, content, buttons, etc.

What Is Back-end Development?

The primary role of back-end developers is to build the aspects of websites that are not visible to the users when they are navigating. These aspects are what make the website truly engaging and interactive. Users are indirectly exposed to these sides of the website; for example, when they are filling out the inquiry form detail or when they are making a purchase through the site. Although back-end development primarily entails the storing and organizing of data, developers also have to ensure that their work does not disturb front-end aspects that are already in place.

Back-end development is commonly referred to as the ‘server-side’ of a website. It involves creating a secure storage space to manage all the data coming through via users who are interacting with the website. This space is called a database. A back-end developer is expected to be capable of managing this database and the information stored in it. Developers also work on creating code, identifying bugs and debugging applications, framework utilization, database management, and more.

Front-end vs. Back-end Languages

Programming languages are the crux of coding. One of the major differences between front-end and back-end development lies in the programming languages that they use. Back-end developers create codes in different languages. These codes are essentially instructions that establish communication between computers and programmers.

Front-end developers work with these primary languages:

  1. HTML (HyperText Markup Language) – a standard markup language used to build webpages. Hypertext defines the link between the web pages. The markup language is used to define the text document which defines the structure of web pages.
  2. CSS – is short for Cascading Style Sheets, and is used to bring style and personality to the website.
  3. JavaScript – a language that can be used to make a website dynamic. It can effectively and efficiently inspect, manipulate and validate data.

Back-end developers work with these primary languages:

  1. Java – a highly popular platform, an object-oriented, write-once-run-anywhere, server-side programming language.
  2. Python – a general-purpose coding language designed to promote code readability. It is simple, straightforward, and versatile.
  3. Node.js – an open-source, cross-platform server environment that helps developers track, motor, and handles data and responses between the client-side and the server-side.

Key Differences Between Front-end and Back-end Development

Front-end Development Back-end Development
   
Commonly referred to as ‘client-side’, front-end development involves the creation of the visual elements of a website or app vis coding – all while keeping the user at the center of it all. Often referred to as ‘server-side’, back-end development focuses on the website aspects that users can’t see; functional elements like contact forms, interactive elements, and purchase options.
   
Some of the most popular front-end languages are HTML. CSS, and JavaScript. Some of the most popular back-end languages are Java, Ruby, Python, and .Net.
   
Key tasks of a front-end developer: Streamlining user experiences by bringing website design to life, developing visually appealing user interfaces, implementing the design on mobile websites, and building features that ensure site interaction. Key tasks of a back-end developer: Making the websites interactive and dynamic, being fluent in database management and all the tools associated with it, creating code, and debugging applications.
   
Front-end involves working with a set of libraries like AngularJS, React.js, jQuery, etc. The list of back-end frameworks includes Express, Django, Rails, Spring, Laravel, etc.
