Solution retrospective


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

This project really opened my eyes on how forms works and how DOM in general works.

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

Adding eventHandler to a button in a form and expect some input to behave in certain ways, i had to do a whole lot of research to come up with a solution.

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

None for now.

    Hey Joel 👋, Great job on completing the Tip Calculator project! 🙌

    Here’s what stood out to me:

    What you did well:

    The UI is clean and matches the design really well.

    The functionality works smoothly across different tip percentages.

    It's great to see it built with React — your component structure is clean and easy to follow.

    Nice use of controlled inputs and real-time updates!

    Suggestions for improvement:

    You could add validation for when users leave fields empty or input zero values — maybe a small warning or disabled button.

    Consider adding a reset button to clear all values.

    Accessibility could be improved with labels or ARIA attributes for better screen reader support.

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.
