Solution retrospective


What are you most proud of, and what would you do differently next time?

I'm proud of the fact that I completed the form validation myself using a mix of the Constraint Validation API and my own custom JavaScript code. It seems I couldn't implement all of the validation requirements using the native API's. e.g. using the attributes of input type number.

Even though I was successful it was cumbersome to implement. I'd like next time to consult the options of form validation libraries that might make this process easier.

What challenges did you encounter, and how did you overcome them?

There were a couple. first was the form validation. then the animation of the numbers for that I used the React Animated Numbers library. but since the font used for the challenge has different widths for the number glyphs. there was excessive spacing between some numbers. so I wrote some unconventional code to add some negative margins to the small numbers.

What specific areas of your project would you like help with?

As always I'd like to know if my code is understandable, readable and follows best practices.

Thank you for viewing my solution!

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.
