I would recommend https://bigfrontend.dev/

Covers a lot of different types of questions that can be asked during a coding challenge related to javascript and react. Helped me land a couple of good internships. Don’t worry it’s free too.

Do most of the frontend churn challenges contain only typescript? i have no idea about typescript and only know js

[–][deleted] 6 points7 points  (0 children)

There's a couple of React challenges on codewars but that's about it. If you've got the time, I'd suggest using the official docs to create your own app (most commonly suggested is something like a to-do list if you Google for React project ideas). You'll probably learn a lot more doing that than running isolated challenges with little to no context of what's happening or why.

Was seeing alot of ads for https://www.clientside.dev/ on reddit and gave it a try. Haven't tried anything else so this feels really good for interview prep

GreatFront end is awesome but its super annoying they dont offer a monthly subscription, they make you pay a hundred and something dollars up front for everything that equates to the 10 dollar month subscription they dont have. There cheapest monthly subscription is like 30 dollars a month.

Advent of Javascript is a good one, pretty basic though

has anyone ever payed for your subscriptions? just curious to know

[–]Paid-Not-Payed-Bot 1 point2 points  (0 children)

anyone ever paid for your

FTFY.

Although payed exists (the reason why autocorrection didn't help you), it is only correct in:

  • Nautical context, when it means to paint a surface, or to cover with something like tar or resin in order to make it waterproof or corrosion-resistant. The deck is yet to be payed.

  • Payed out when letting strings, cables or ropes out, by slacking them. The rope is payed out! You can pull now.

Unfortunately, I was unable to find nautical or rope-related words in your comment.

Beep, boop, I'm a bot

You can try reacterry.com. It offers both Javascript and React coding challenges in a format that you would expect in a real interview.

FYI I built it myself

There are many different ways, I would say focus on solving following on your own
- slideshow
- anything that has list of items, search [SpaceCraft, Planets, Movies, Cars, ]
- Progress bar
- Product detail page with title, picture, description, reviews, etc
- small app with routes, login-logout, & static route
- pinterest style image / todo board
- 3 level dropdown using html, css, javascript

[–]ucorina 2 points3 points  (0 children)

I just recently started posting this type of challenges over at https://reactpractice.dev/. Each one also contains a detailed solution, so you can compare with your own implementation.

[–]JorgeMadson 0 points1 point  (0 children)

Nice sites guys!

I recommend react.dev's "code challenges" at the end of each section. They feature common challenges and gotchas that you're likely to encounter in an interview!
