We will not hide it from you, the WeLoveDevs app is made in React ⚛️. We really like React !

This quiz contains a large part of the concepts to know about this library.
There are questions before hooks and questions after hooks, but you should be able to get by with a little practice :)
This test only talks about react. There are therefore very few (one or two) questions relating to peripheral libraries (redux, jss, material ...)

It tests the following skills:

  • describe a UI with React ⚛️
  • how to manage the state of a component
  • how to organize its components
  • how to manage the state of components
  • optimize rendering
  • detect and fix bugs in React code
  • API hooks
This test consists of 20 questions randomly selected from a database of 37 questions in React.Discover all our interview questions and answers here

Test author : La team W3D 💙

Clément and Vincent are two developers at WeLoveDevs.
Our stack is based on React, Firebase and Javascript / Typescript, so we spend a lot of time to experience the specifics of React ⚛️.
We think that this quiz allows to test the capacities of a developer who already has a few experience with React.
