Solution retrospective


This was a really fun project! This app was a bit tricky at first since I've never developed a quiz app before, but I learned a lot of different techniques to implement a component and re-use it.

The hardest part was implementing a component that displays ALL the questions from a specific quiz. I had to make the component dynamic so that it can render all the questions with their respective choices.

I ended up using Redux to keep track of the question that the user is currently on. When the user clicks on the 'Next Question' button, it updates the global store to ensure that the state 'points' to the next question.

For example, when the user starts the quiz, the global store has a property called 'currentQuestionNumber' and it is initialized to 0. Once the user clicks on 'Next Question', then the currentQuestionNumber will be incremented by 1. Now we have ensured that the state points to the next question.

I HIGHLY recommend you try developing this app!

How does the accessibility report work?

When a solution is submitted, we use axe-core to run an automated audit of your code.

This picks out common accessibility issues like not using semantic HTML and not having proper heading hierarchies, among others.

This automated audit is fairly surface level, so we encourage to you review the project and code in more detail with accessibility best practices in mind.

How does the CSS report work?

When a solution is submitted, we use stylelint to run an automated check on the CSS code.

We've added some of our own linting rules based on recommended best practices. These rules are prefixed with frontend-mentor/ which you'll see at the top of each issue in the report.

The report will audit all CSS, SCSS and Less files in your repository.

How does the HTML validation report work?

When a solution is submitted, we use html-validate to run an automated check on the HTML code.

The report picks out common HTML issues such as not using headings within section elements and incorrect nesting of elements, among others.

Note that the report can pick up “invalid” attributes, which some frameworks automatically add to the HTML. These attributes are crucial for how the frameworks function, although they’re technically not valid HTML. As such, some projects can show up with many HTML validation errors, which are benign and are a necessary part of the framework.

How does the JavaScript validation report work?

When a solution is submitted, we use eslint to run an automated check on the JavaScript code.

The report picks out common JavaScript issues such as not using semicolons and using var instead of let or const, among others.

The report will audit all JS and JSX files in your repository. We currently do not support Typescript or other frontend frameworks.
