Solution retrospective


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

I’m most proud of building a fully functional and interactive Tic-Tac-Toe game from scratch using only HTML, CSS, and JavaScript. This includes core logic like turn management, win detection, dynamic SVG rendering, player vs CPU mode, and saving match history in localStorage.

What made me especially proud was implementing:

Smart CPU logic that can block or win strategically.

Real-time UI updates with visual feedback (colors, icons, indicators).

A modular and organized code structure that separates logic, storage, and UI.

A user-friendly experience that works on desktop and mobile.

What I’d do differently next time:

Use TypeScript or modular JavaScript to improve type safety and reusability.

Implement a settings panel to reset the board, clear history, or change difficulty level.

Add animations or transitions to make gameplay feel smoother.

Improve accessibility (ARIA roles, keyboard support).

This project taught me a lot about DOM manipulation, event handling, and how small projects can become powerful learning tools when built with attention to detail.

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

The DOM manipulation, the cpu logic, the localStorage, a lot of work, I hope it turned out well.

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

I would like general accessibility and javascript tips on modules and general logic, I might be a bit messy in the code.

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.
