Frequently Asked Questions

The front-end goes far beyond classic graphic design – your app should tell a story. We, at Mega Sup, know how to tell your story using proper layout, well-thought navigation, functionality, and usability and make your product stand out. Our team of front-end developers experienced in React.js, Angular, Vue.js, JS, Ember.js and many other frameworks and libraries shares its accumulated knowledge in various aspects of front-end development:

Front end development refers to the process of creating the visible parts of a website or web application that users interact with directly. It involves crafting the layout, design, and functionality of the user interface using various technologies such as HTML, CSS, and JavaScript.

Front end developers focus on designing and developing the user interface that users interact with directly. They work with technologies like HTML, CSS, and JavaScript to create visually appealing and responsive web interfaces. Backend developers, on the other hand, handle the server-side of the application, managing databases, server logic, and ensuring data flows smoothly between the front end and back end.

Several languages are commonly used for front end development. HTML is used for structuring the content, CSS for styling and layout, and JavaScript for interactive and dynamic features. Additionally, popular JavaScript frameworks like React.js, Vue.js, and Angular are widely used to streamline and enhance the front end development process.

Front end development is crucial as it directly impacts the user experience. A well-designed and user-friendly interface enhances user engagement, satisfaction, and retention. An efficient front end ensures that websites and applications are responsive across devices, load quickly, and provide seamless interactions, contributing to the overall success of a digital product.

Vue.js and React.js are both popular JavaScript libraries used for building user interfaces. While both offer reactive data binding and component-based architecture, they differ in their approach and ecosystem. Vue.js is known for its simplicity and ease of integration, making it a good choice for smaller projects. React.js, developed by Facebook, has a larger community and is commonly used for complex applications, offering better performance and a more extensive set of tools.

In the Vue.js ecosystem, the most common dependency injection library is "Inversify-vue", which brings the concept of dependency injection to Vue.js applications. This library allows you to manage and inject dependencies into components, promoting modularity and maintainability in your Vue.js projects. By utilizing dependency injection, you can decouple components and manage their dependencies more efficiently, resulting in cleaner and more scalable code.
