10 ReactJS Coding Challenge (💥Coding Interview Prep💥)

Last month, I posted 2 ReactJS interview questions 🎤 - Advance Questions and Commonly Asked Question and got a significant welcome by dev.to community. 🤗 🥰 Many thanks to all of you!

I decided to complete the package by creating codepen exercises 📝 and a video 📺 to follow up on that effort as one will need to code following the technical interview questions. Also, I added potential solutions for the exercises which is listed below.

If you need to brush up 🆙 your ninja ReactJS skills, you can try to answer the exercises below OR click the video below to guide you step-by-step interactively. (No filler, fast, straight to the point as I highly respect/value your time)

These exercises and solutions will also be available on the video as well.

Exercises: 🏋️

Display simple JSX

Display array of users to browser

Show/Hide Element on Screen

2 way data binding in ReactJS

Disable a button

Update the parent state

Dynamically add child components (React Children)

Sum of Two Numbers

Create Counter App

Fetch data from an API
