Solution retrospective


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

I'm proud that I managed to complete the project and I will probably make my form handling more dynamic.

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

My main challenge was making the input tags to be formatted and handled correctly by my various functions and I overcame it by switching to input of type text added the necessary functions for formatting and updated my validation functions to accept data attributes for the validation.

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

    About the input tags formatting. It's a delicate job what you've done, but maybe more simplicity would make the code more legible. I develop:

    x = yourinput.value;      // comes as a string, e.g. "300,000"
    x = x.replace(/,/g, ''); // replaces all (g of global) commas for blank spaces, e.g. "300000"
    x = parseFloat(x);      // tries to convert to float
    if (isNaN(x)) { 
        dont allow calculate
    } else // is number
        allow calculate
    

    A method like that, of course applied to all inputs before you can press the calculate-button, would be more efficient in my opinion. Finally, I did apply the mentioned method in the calc-button.listener, if you need to check.

    Great job even so, nice CSS. Cheers @CardboardPL.

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.
