Я не пытался тут собрать все вопросы, которые хорошо бы задавать, а лишь те, что мне задавали (если не указано обратное), так что не неситесь жаловаться, что вы не нашли своих любимых и коварных. Так же, я не привожу список всяких логических задачек, которых, слава богу, было минимум и задачек с написанием кода на листке бумажки что, к сожалению, всё ещё распространено.

React:

• Жизненный цикл компонента? В какой метод какие аргументы приходят? Где и как лучше обновлять стейт?
• Что такое функциональный компонент и PureComponent? В чём разница?
• Что такое Redux?
• Что такое сайд-эффекты?
• Какие бывают миддлвары в Redux?
• Для чего нужен redux-thunk?
• На чём построена redux-saga (на генераторах) и для чего она нужна?

Proposal for lightning talk at Reactive Conference.

===

Use case for react-native-macos

React Native for macOS (a.k.a React Native Desktop) started as an experiment a year ago, just out of curiousity and the active stage of development also took place during the previous Reactive conference right in the hotel room in Bratislava.

5 minutes talk about why you probably haven't heard about any real desktop application based on RN, and for what kind of applications it might be perfect fit.

A life on a Commandline

As a JavaScript developer, could you imagine using something else than Atom, Sublime or other IDE-like text-editors? During their daily work, people wrangle a lot with different applications, editors, windows, browsers and loose a lot of time because of their tools getting in their way.
