Thanks for nice challenges. I really enjoyed solving them! By the way beta.reactjs.org/ also started to include challenges. Maybe you can contribute to the new docs? They are open for public PRs.
your welcome! ill definitely check that out. thanks for the link.👏🏻👍
Hi armenic,
I want to contribute new challenges in beta.reactjs.org/. I don't know how to contribute, I saw React's git repo but I didn't understand how to start. can you please guide me.
check this out - reactjs.org/docs/how-to-contribute...
Great exercises! Had fun with these!!
One thing I want to note - in your solutions, I often see the pattern:
However, the React docs prefer this method of using the previous state value - passing a function that receives the previous state value.
Updating state with
value
instead of using the previous state function may result in some buggy behavior because of React's unpredictable & async state-updating logic. Likely won't see anything buggy with these examples since they aren't too complex, but just wanted to shout out that nuance!Thanks again for these great exercises!!
yes, passing a function is way better and the right approach to handle setting state here. Glad that you found this post useful and you are very welcome. Will create more post/video like again.
It was fun! Thanks a lot!
glad that you've liked the coding exercises! thanks for the comment.
I found this on udemy.
React JS Coding Interview Challenges and Exercises
udemy.com/course/react-js-coding-i...
its good.
Nice I always look for those kind of challenges to practice
i plan on making more in the future. Stay tuned :)
Very helpful exercises for beginners. Thank you :)
thanks for that nice chalanges
your welcome buddy! i feel great that this content helps many devs. 👍
It's difficult for beginners (like me) to directly dive into building projects after learning React from online tutorials. Thanks for these practice problems, need more of these on React. :)
ive been there before and i know how you feel. i’ll try to find more time and do more. i’ll post when i have something ready. thanks for the comment
this is so helpful for interview prep, thank you!!
helping engineers like you and me are the goal of this post and video.
I appreciate the comment and stay tuned for more post like this.
For create counter app challenge, i created two functions (decrease and increase) to be passed instead, later simply calling ....is that inline with best practise?
it is and is common in any ReactJS applications
I enjoyed this! Thank you so much!!! If anyone have anything similar please share! I would love to tackle on some more!
Thank you in advance!
you are welcome!
This was so helpful, thank you!
your welcome Veronica! check the youtube video i have above for additional reference. Many found it useful as well.
Out of curiosity, if you could do all of these quite easily without any external help/docs, is that a good sign you might be ready for a React Junior Dev role? 🤔 Or would we need to be answering the advanced ones?
this is question is more tailored for experienced/advanced React Dev.
you can expect basic Q&A for React Junior Dev and small react exercises
I found these exercises are too easy. Could you please mention that these are for absolute beginners somewhere in the header of the post? I doubt that any interview question would be this straight forward. Nevertheless, appreciate your effort on making the post, it has to be useful for someone 👏🏻
too easy for interview, look real example
https://stackblitz.com/edit/stackblitz-starters-rqq4bw?description=A%20create-react-app%20project%20based%20on%20react%20and%20react-dom&file=src%2FApp.js,src%2Findex.js&title=React%20Starter
you can make that all works as expected, but wont pass interview because of interviewer wants you write some functions in other way
and you can forget some things because of worrying
For me (beginner), this is very helpful and gives an overview of the interview later. Thank you for sharing
absolutely! what is your status currently? are you in the job market?
Good job man. Intresting exercises.
thank you Anand! What is your favorite exercise and why? Or perhaps anything that you would like to see on the challenge.
hey bro please make more challeneges like these.. i want some hard level questions
Very helpful for me. Thank you.
of course. very welcome and happy to help
think you i really enjoy the challenge
i am glad you feel that way
That challenges too easy! Like for the junior level.
I would be glad to see more complecated challenges from you :)
sure. I can take it up a notch
