Top Frontend Interview Questions For Meta

Frontend is an important component of any application, website, or platform. It is responsible for the user interface and how users interact with the application. Frontend development involves creating and implementing the visual components of a website or application, including the layout, styling, and structure of the user interface. Frontend development is an ever-evolving field, with new technologies and frameworks constantly emerging. The goal of frontend development is to create an intuitive and streamlined user experience while also meeting the requirements of the project. Frontend developers must have a strong understanding of HTML, CSS, and JavaScript, as well as an understanding of best practices and design principles. For web applications, the use of HTML allows developers to create the structure of the page, while CSS can be used to customize the look and feel of the page. JavaScript is used to add interactivity and dynamic elements to the page. Ajax is a popular way to create dynamic and interactive web applications. When developing mobile applications, the frontend is often built using a mobile framework such as React Native or Flutter. These frameworks allow developers to quickly create user interfaces for mobile devices and provide a good starting point for creating more complex applications. Frontend development is a key component of any project and requires careful planning and implementation. When building a website or application, the frontend should be the first area of focus, as it will determine how users interact with the project. It is important to ensure that the user experience is intuitive, engaging, and responsive.
