Front-End Interview Preparation Bootcamp | Day 5 | Summarizing Frontend Concepts

Welcome to Session 5 of the Front-End Interview Preparation Bootcamp by ‪@CodeKerdos‬ ! In this session, we discuss practical frontend engineering scenarios that frequently come up in interviews. The focus is on making the right architectural decisions, managing application state, improving performance, handling unreliable networks, and building better user experiences. Instead of simply learning definitions, we explore how to approach real-world frontend problems and explain our decisions clearly during technical interviews. Topics covered in this session: 1. Writing Maintainable React Components Breaking large components into smaller, reusable components Separating custom hooks, utility functions, and API logic Improving code organization and maintainability 2. Choosing the Right State Management Approach Local UI state vs shared application state Managing authenticated user details, themes, and shopping cart data Context API vs Redux Understanding server state and client state Using browser storage such as localStorage and sessionStorage 3. Handling Shared Data Efficiently Avoiding redundant API calls Sharing fetched data across components Using caching and global state appropriately 4. Improving Loading Experiences Skeleton UI vs traditional loading spinners Implementing optimistic UI updates Improving perceived performance and user experience 5. Frontend Bundle Size Optimization Identifying unnecessary dependencies Analyzing bundle size Compressing assets Code splitting and route-based lazy loading 6. Handling Unreliable Networks Designing for network failures Implementing retries with exponential backoff Checking network connectivity Providing meaningful feedback when the application is offline 7. Real-Time Data Updates Polling WebSockets Server-Sent Events (SSE) Choosing the right approach based on update frequency, latency, and communication requirements WHO SHOULD WATCH THIS SESSION? Frontend developers preparing for React interviews Developers with experience in JavaScript, React, and modern frontend frameworks Engineers preparing for scenario-based interview rounds Anyone looking to improve frontend architecture, performance, and problem-solving skills The goal of this bootcamp is to help developers move beyond theoretical knowledge and learn how to approach practical frontend engineering problems with confidence.
