Building an Unbeatable Tic-Tac-Toe Bot with Go and WebAssembly
In this tutorial, we’ll explore the world of Artificial Intelligence (AI) by building a bot that can play tic-tac-toe perfectly. We’ll use the Go programming language to create the bot’s logic and then integrate it with a React front-end using WebAssembly.
The MiniMax Algorithm
The MiniMax algorithm is a decision rule used in AI to minimize the possible loss for a worst-case scenario. In the context of tic-tac-toe, our bot will use this algorithm to choose the path that gives the opponent the lowest opportunity to win.
Implementing MiniMax in Go
We’ll start by creating a new Go file called tictactoe.go. In this file, we’ll define a function called GetNextMove that takes the current game state as input and returns the best move for the bot.
“`go
package main
import (
“fmt”
)
func GetNextMove(state [3][3]int) (int, int) {
// Implement the MiniMax algorithm here
}
“`
Integrating with React using WebAssembly
To integrate our Go code with a React front-end, we’ll use WebAssembly. We’ll create a new React app and then import our Go code as a WebAssembly module.
“`jsx
import React from ‘react’;
import ReactDOM from ‘react-dom’;
import { Go } from ‘./go’;
const App = () => {
const [gameState, setGameState] = React.useState([[0, 0, 0], [0, 0, 0], [0, 0, 0]]);
const handleMove = (x, y) => {
// Call the GetNextMove function from our Go code
const nextMove = Go
