UnderstandingModern Front-endDevelopment

Abstract - Over the years, the way we build web interfaces has transformed dramatically. What began as simple static pages has evolved into complex, interactive applications designed for an ever-growing array of devices. This review takes a deep dive into today’s front-end development—exploring the core languages (HTML, CSS, JavaScript) alongside the frameworks and tools that have expanded their capabilities. It covers best practices in responsive design, performance enhancements, and cross-browser consistency while also addressing challenges like security and accessibility. Emerging technologies such as WebAssembly, Progressive Web Apps (PWAs), and AI-enhanced development tools are discussed as indicators of where the industry is headed.
