I Created 500+ Dev questions and Launched a Quiz platform 🏆🎉

#webdev #showdev #nextjs #productivity

Companies usually want to test a specific area of knowledge. Quizzes are an engaging method to measure your expertise in the particular field.

That's why I created DevQuizzes, an online platform where you can test your knowledge across various DEV topics.

Content

Over the last 6 months I read a lot of official documentation and studied dozens of tutorials to create the content basis for initial launch.

I ended up creating over 500 questions in 20 categories.

Numbers in the parentheses show the questions in each quiz. Grey color represents the quizzes in progress, while white - all the new ones.

Percentages are shown just for completed quizzes, with green and red colors representing the passed and failed quizzes, respectively.

Quiz

When a category is selected, user gets presented with a quiz. By default unanswered questions are shown first.

Each question usually provides 2 to 4 possible answers. For the reference each question has a topic/title.

The next question is only available if the current question is answered. The previous questions are available as soon as there are some.

When provided, user can click a Hint button. This way an additional information about the question will be revealed.

Some questions do provide a code snipped, which the question is based on.

Progress

All the progress is stored in the Local storage.

Users are also able to clear the Local storage, for both - all quizzes at once or any particular quiz separately.

At any point during the quiz, the user has an access to the list of questions, meaning the questions can be manually picked or reviewed later.

Rewards

After completion of the quiz, user gets awarded ether gold (>90%), silver (>75%), bronze (>60%).

If user scores in the range from 60% to 40%, test is passed but no award is given. All the results below 40% fail.

Users have an option to share their achievements in social media.

Contributions

Everyone is welcome to submit questions via Airtable form.

Questions will be accepted unless they duplicate an existing content. The database will be updated daily.

Each contributor gets credited as well as included in the the most recent and/or most active contributors list in the Top section.

Final notes

The project is live, feel free you try it. The quiz platform is responsive, meaning it is easy to play on both desktop and mobile devices.

I'm hoping the project will help the community. I'm also looking forward to add questions and features to the platform itself in the future.

If you have any questions, feel free to reach out!

Hi Madza, this project is super nice, congratulations.

I've taken the git quizz and found a little mistake, there is this question:

Which of the following commands is used in
switching between branches?

- git switch
- git checkout
- git branch
- git change

The correct answer can be git switch or git checkout depending on the git version.

git checkout was introduced on version 2.4

git-scm.com/docs/git-checkout
git-checkout - Switch branches or restore working tree files

git switch was introduced on version 2.27.x

git-scm.com/docs/git-switch
git-switch - Switch branches

git switch was added to make the commands more precise, (git checkout had too many responsibilities), now instead of using git checkout to switch branchs or restore tree files we have two new commands:
git switch and git restore

Thanks for the contribution! I've edited the question and included you in the Top contributors list 👍🏆
Also you can submit edits directly from the platform... As soon as each question is answered there is an Edit option on the left. 😉

FL Studio crack? 👀 What is this, lol 😄😄

Looks neat - how often have people been asken when SQL was invented?
I find that knowledge irrelevant when measuring how good I am.

andy • Jul 15 '21

How often? Never. The only reason I knew it was I was taught it in college in 1988 and remember it had been round for yonks already.
There has to be some advantage of being old, yes? :D

Neat project Madza - looks & works awesome!

Madza • Jul 15 '21

Thanks a lot for trying out the project 👍😉

Madza • Jul 15 '21

Thanks 😉 Let's just assume, it goes out to show how rock solid it has been through the years, still being as relevant as ever 💪😀😀

That’s what I call a full bundle, awesome work, fella! 🔥🔥🔥🔥

Madza • Jul 15 '21 • Edited

Thanks so much 🙏❤ Means a lot 😉

Great! Just one thing: Can you open-source the project? Thanks.

Madza • Jul 15 '21 • Edited

Thanks a lot! 😉
Currently no plans to do that as both the platform itself and the questions are stored in a single GitHub repo. Going open source would sooner or later cause someone to clone all the content, deploy it under their own domain and claim it as theirs, the sad truth I've learned from blog posts and other content 😉
If I ever decide to do backend and move questions to DB, I might re-consider to open source the platform itself. 😉
