Solution retrospective


👋Hello, I'm Vinicius.

👨🏼‍💻This is my solution for the Tic Tac Toe game

🛠️ Built with

  • Semantic HTML5
  • Styled-Component
  • TypeScrpt
  • ReactJS

📜 What I learned?

I learned more about the hook useReducer. My previous code was messy with useState. I hade a lot of state to take care of. So I studied about this awesome hook and now the code is much better.

With useReducer, I can build more complex state and change it at once with one function.

😁 Thanks

I'll be happy to hear any feedback and advice!🤗

Thank you very much

    Heyo,

    This is awesome and for the most part it works great. Few things I noticed:

    • The url you provided for the site brings me here: https://tic-tac-toe-react-two-sand.vercel.app/game instead of here: https://tic-tac-toe-react-two-sand.vercel.app/. This is obviously an issue, since the player hasn't selected a game mode, the game just lets you put in as many O characters as you want. I'm guessing some states are missing and causing this bug. You should change the url in this submission but even so, it's a good idea to protect your routes against stuff like this and only let the /game page be accessible if the game mode has been selected (it could just automatically redirect to the homepage if no game mode is selected).
    • you might want to consider having the game logic somewhere else than the App.tsx, it looks a bit chaotic at the moment. Creating a context might be a good solution.
    • If I start a game (Player vs. CPU) and make a few moves without finishing it, then navigate back to the homepage to start a new game, the game isn't being reset, I'm met with the game I left off previously. Would be nice if the New Game option would start a new game everytime, regardless of previously existing sessions.

    Apart from these few small bugs, what you did is really impressive. The design looks on point. Well done!

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.
