About
FrontendAtlas is a front-end interview preparation platform built around hands-on practice rather than passive content. It provides an in-browser coding workspace with files, tabs, and split panes, where you solve UI-first coding prompts and validate results using live previews and deterministic checks/tests. The library includes hundreds of interview questions across React, Angular, Vue, JavaScript/TypeScript fundamentals, and HTML/CSS, plus front-end system design scenarios focused on constraints and tradeoffs such as caching, pagination, state management, and performance budgets. The product also includes debugging simulators and “tradeoff battles” to practice explaining decisions under pressure. Work is saved locally in the browser for repeat sessions, and users can follow structured tracks (e.g., 7-day sprint or 30-day foundations) to reduce decision fatigue and build consistent preparation routines.
