Please answer the questions on the next page for us to understand you as a front-end developer better. To give you a rough picture about what the answers might look like, here’s the question/answer from one of our recently joined colleague.

What do you think is the trickiest part about using React?(or any major framework/library you used)
The trickiest part of using React to develop is the best practice is changed rapidly. When the state management tool - Redux introduced, the concept of the container and presentational component is also defined and followed by the community as the best practice at that time. As time passes, the best practice has changed along with community discussion - the container component should not be defined against the route pages as when it was introduced but split to smaller ones match conceptual modules. As now, with the React Hooks API, the boundary between the container and presentational component becomes more blurry. Technology changes fast, and the best practice using the technology changes too. Understand how new approaches would benefit your project and adapting them is the trickiest part, in my opinion.
