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:The correct answer can be
git switch
orgit checkout
depending on thegit version
.git checkout
was introduced on version2.4
git switch
was introduced on version2.27.x
git switch
was added to make the commands more precise, (git checkout had too many responsibilities), now instead of usinggit 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 ππ
Also you can submit edits directly from the platform... As soon as each question is answered there is an Edit option on the left. π
FL Studio crack? π What is this, lol ππ
Looks neat - how often have people been asken when SQL was invented?
I find that knowledge irrelevant when measuring how good I am.
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!
Thanks a lot for trying out the project ππ
Thanks π Let's just assume, it goes out to show how rock solid it has been through the years, still being as relevant as ever πͺππ
Thatβs what I call a full bundle, awesome work, fella! π₯π₯π₯π₯
Thanks so much πβ€ Means a lot π
Great! Just one thing: Can you open-source the project? Thanks.
Thanks a lot! π
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 π
If I ever decide to do backend and move questions to DB, I might re-consider to open source the platform itself. π
Awesome, thanks for this!
Great to hear and you are welcome! ππ
Wonderful!
Thanks a lot ππ
Could add Python as one of the sections?
Python is def planned in the future π
For now I added it as submit option if users have ideas for questions π
Oh okay :)
Awesome project ! Really Enjoyed it π
Happy to hear! π Thanks! ππ
Congratulations for the launch πππ½
Thank you so much ππ
I found a few issues/misleading questions in the JavaScript quiz:
Q9:
The answer on the quiz is
onClick
, but I thinkclick
is the valid answer.element.onclick
is just one way to define a click handler, the other beingelement.addEventListener('click', () => {})
. Mozilla even calls it the "click event" (developer.mozilla.org/en-US/docs/W...)Q12:
The answer in the quiz is
True
, butDate
can also accept a string as a single parameter, which will be parsed. So I think this question is misleadingQ38:
I think the question was supposed to read "What character is used for the remainder operator in JS?"
May I suggest adding a way to provide feedback from within the site?
Overall though, it's a super nice way to test your knowledge!
Thanks for the input! ππ
Just fixed the questions you noted π
I might implement feedback from a site in the future π
Just checked it out it looks cool and a lot of fun π
Thanks so much ππ
Hopefully it helps the community ππ
This is pretty awesome! I did a similar thing in the past with the Quiz API website π
Why is github Auth system broken?
Iβll look into it
Awesome π I see you have extended the functionality by providing an API to embed quizzes on external websites π Very handy π
Congratulations for the launch π₯³
Means a ton, thanks ππ
Found a question with a wrong answer
Here a picture
dev-to-uploads.s3.amazonaws.com/up...
Thanks for the input! π Fixed the question.
I've also added a functionality for users to edit questions directly from the platform π
Thanks for the input ππ
What's the category and name, so I can fix it? π
