## Overview

This is a browser-based, two-player tic-tac-toe game. Its workflow initializes player names and X/O pieces, lets players mark the board in alternating turns, checks for a winning line, and allows a restart. The game logic and player setup are implemented in one JavaScript file; the page is represented separately. The excerpts do not show how moves are wired to user input, so that connection is left unverified.

Main entry points: [`index.html`](https://github.com/alinealien/jogo-da-velha/blob/main/index.html) (Game Page), [`src/scripts/velha.js`](https://github.com/alinealien/jogo-da-velha/blob/main/src/scripts/velha.js) (Win Detection)
