Solution retrospective


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

For some weird reason the javascript parts of these projects comes easy, even easier than the css.

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

The challenges i encountered where the layout which took me extra ours than i had planned and the cases in my javascript calculaion where the calculations where reading 'infinity' or NaN both i fixed all that. T

    Really nice job!

    In my solution i just focused on the validations a lot and that made sure that i did not have to handle those cases where the results would be weird values because the user cannot input invalid numbers such negative ones or zero.

    I see your solution does not do validations at all and still outputs infinity and such, should add those form validations in.

    You can checkout mine for help, overall very nice solution, styling is very good, did not know you could nest classes like that.

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.
