What's the Difference Between Front-End and Back-End?

Frontend and backend are two pillars of web development. It’s similar to the movie-making business. The front-end is what we see on the screen, while the back-end is where all the technical work happens like editing, lighting, etc.

Front-end and back-end web development

All the visual elements of a site or app that we see or experience are a part of the frontend, whereas all that happens behind the scenes are a part of the backend.

We can interact with the front-end components of a website, such as the graphical user interface (GUI) and command line, which includes navigation menus, texts, videos, design, and images. On the contrary, we can’t see or interact with the backend side.

Front-end Languages are HTML, CSS, and JavaScript, while back-end languages include Python, Java, PHP, Ruby, etc.

What is Frontend Development

Front-end development focuses on that part of the website that users see and interact with. It is also known as the client side of a website and includes everything that affects user experience, such as images, text colors, buttons, graphs, tables, themes, navigation menu, videos, etc.

User experience (UX) and user interface (UI) designers work with developers to bring a website to life by ensuring each visual and design element is placed correctly. They use HTML, CSS, and JavaScript languages for front-end development.

As we discuss backend vs frontend development, it’s important to know that both aspects have different goals. Front-end development has two primary objectives- responsiveness and performance. Responsiveness ensures that the website or app is compatible with all devices, and performance means that all elements must function properly.

How does the front-end aspect of an application work?

Frontend of a website includes the graphical user interface (GUI) that users interact with directly, which includes design elements, graphs, navigation menus, buttons, etc.

There are three main programming languages that affect user interaction with frontend:

HTML is used to define the frontend structure and different DOM elements.

CSS styles the web app, including fonts, visuals, layouts, and colors.

Javascript is used to add a layer of dynamic functionality. It handles fundamental user interactions, such as ensuring that the user has entered a valid email address or displaying a calendar. It passes more complex requests to the backend.

Front-end Development Languages

Another difference between frontend and backend is the languages and frameworks used. Below, we’ll discuss front-end development technologies, languages, and frameworks.

1. HTML

Hypertext Markup Language (HTML) is used to design the structure of a website. It includes images, texts, and hypertext that defines links between web pages. HTML enables users to navigate easily from one page to another and offers a user-friendly platform to format documents.

2. CSS

Cascading Style Sheets, or CSS, is a programming language used by developers to customize a website and make web pages more presentable. It includes fonts for texts, organizing texts, and color schemes.

3. JavaScript

JavaScript is a scripting language used to make a website more interactive by adding interesting elements and effects to the web page. It includes embedded media, animated images, and active content that improve the functionality of a website, especially for fun video games and web-based software.

JS is used in front-end and back-end development, which makes it one of the most sought-after skills for a successful developer.

There are several other front-end web development programming languages, and you can choose the best one depending on the framework. For example, React uses JS, Flutter uses Dart, and Django uses Python.

Front-end Frameworks and Libraries

Apart from frontend and backend programming languages, the frameworks and libraries used in both are also different. Take a look at some of the popular front-end frameworks and libraries:

1. AngularJS

Angular js is an open-source framework used primarily for the development of single-page web applications (SPAs). It was introduced by Google in 2010, and the current version of this framework was released in 2016 to enhance the technology and overcome the restrictions of traditional frameworks.

Angular is constantly expanding and growing to provide better web application development methods. Similar to React, this JavaSCript framework is used for creating user interfaces.

2. ReactJS

ReactJS is another JavaScript library used to design user interfaces. It was developed by Facebook and has a huge community of contributors to ensure its consistent evolution. It is efficient, declarative, and flexible, with a shallow learning curve, which encourages beginners to learn it.

ReactJS is a component-based and open-source library that takes care of the view layer of the app. Moreover, it makes front-end development hassle-free, and its distinct feature is its Virtual Document Object Model (DOM).

3. Vue.JS

Are you familiar with Frakenstein’s monster? Do you know how to create a powerful result by combining the best bits of what was before? The VueJS is certainly an ideal framework for you. The team at React has leveraged the best aspects of earlier front-end frameworks to design this hyper-functional yet easy-to-learn framework.

4. Bootstrap

Bootstrap needs no introduction as it’s the most popular front-end framework. It is an open-source collection of tools used for building responsive websites and web apps. Developers rely on it for creating mobile-first and responsive websites.

5. jQuery

Jquery is also an open-source JavaScript library used by developers to simplify interactions between HTML/CSS documents, or Document Object Model (DOM), and JavaScript. In simple words, it is a compact, functional, and quick front-end development library that simplifies HTML document manipulation and traversing, event handling, browser event handling, Ajax interactions, DOM animations, etc. With jQuery, you need not write lengthy JS code.

6. SaSS

If you are looking for a mature, reliable, and robust CSS extension language, then SASS is for you. It extends the functionality of the existing CSS of a website, including inheritance, variables, and nesting, with ease.

Roles and Responsibilities of a Frontend Developer

Now, talking about front-end vs back-end developer, they both have different job roles and duties. The former ensures that users interact seamlessly with a website, mobile app, or software without facing any issues. They take care of all visual elements and perform the following tasks:

1. Client Interactions

Before developing a website, front-end developers have detailed discussions with clients to understand their requirements for the project. They listen to all the points clients have in mind and ask the right questions to avoid confusion.

2. Identify Issues

They also evaluate web pages and websites meticulously to identify any errors and fix them so that the site works as intended. The testing process includes assessing the functions and workings of each element that we see on a website, such as buttons, forms, videos, etc.

3. Design Visual Elements

For bigger projects, front-end developers also take care of digital designs, creating graphics, videos, images, and other visual elements on a site. They also select fonts, color schemes, photo placement, layout, forms, alignment, and other pieces to enhance the look and feel of a website.

They are responsible for interacting with project managers, clients, and other stakeholders who have a vision for a website or app. Their aim is to offer a memorable experience to users and provide powerful solutions to clients. Their other job tasks include:

Securing and cleaning code
Turning design ideas into reality
Implementing changes in designs
Managing workflow of an app
Creating and maintaining UI/UX

What is Backend Development?

To gain a fair understanding of front-end and back-end development, let’s now take a look at the meaning of backend development.

Back-end development means designing the architecture of a website, which is invisible to users. It involves all the behind-the-scenes actions that make a website engaging and dynamic. It is also known as the server side of a website, storing and arranging data and ensuring every element on the client side works fine.

Users can’t see or interact with the backend, and this side of the website has no direct contact with them. However, they access these backend elements through the frontend. It includes activities such as creating libraries, writing APIs, working with system components without UI, etc.

For example, when developers build a social media platform, they would need to design a single location to store users’ data. So, they will use the SQL server, MySQL, and Oracle databases as their data storage facilities. Although the database is the root of the backend, it also involves other aspects that we’ll discuss later. Users may not see the back-end portion of a website, but it must be accurate for the proper functioning of a website.

The following are the major components of backend development:

Server- They are used to share data and resources, process computations, and distribute work.

Database- It stores and organizes data.

Application- It is computer software to help users perform specific tasks.

How does the backend of an application work?

The backend is also known as the server side of a website that manages the overall functionality of a website or web app. Whenever users interact with any frontend element, a request is sent to the backend in the HTTP format to process the request and send the response. The backend interacts with the following components:

Microservices- They perform a subset of a task that the user has requested.

Database Servers- To modify or retrieve data.

Third-party APIs- To collect required information and perform additional functions.

The backend also uses different communication protocols and technologies to complete each request. Moreover, it handles multiple requests simultaneously and combines concurrency and parallelism techniques, such as distributing requests across various servers, caching, and data duplication.

Back End Development Languages
