What is fe-interview?

FE-Interview is a Chinese-language collection of more than 1,000 frontend development interview questions, each with a detailed written answer. The project is aimed at developers in China preparing for technical job interviews at software companies. All content is in Chinese. The questions are organized by topic area and span the full range of frontend skills: HTML, CSS, JavaScript, Vue, React, Node.js, TypeScript, Webpack, HTTP networking, browser behavior, algorithms, and security. The repository uses GitHub Issues as the question storage format, with each question posted as an issue and its answer available either in the issue thread or via a linked companion repository. The project also published a daily question cadence, with entries labeled Day 1 through Day 386 and beyond. Each day adds one new question with a worked-through answer, covering practical scenarios like how JavaScript event bubbling and capturing interact, how to implement a countdown timer without drift, or how to design a frontend monitoring system that tracks page performance and error rates. A companion WeChat mini-program (a mobile app format specific to the WeChat platform popular in China) lets readers browse the questions and answers on their phones. The README includes a QR code to access it. This repository is not software to run or a library to install. It is a study resource, a bank of real interview questions collected from the Chinese frontend engineering community, useful for anyone preparing for frontend developer interviews in the Chinese job market.
