Number guess game example (猜数字游戏案例)

const minNum = 1;
const maxNum = 100;
const answer = Math.floor(Math.random() * (maxNum - minNum + 1)) + minNum;
 
let attempts = 0;
let guess;
let running = true;
 
while(running){
 
	guess = window.prompt(`Guess a number between ${minNum} - ${maxNum}`);
	guess = Number(guess);
 
	if(isNaN(guess)){ //isNaN() to check if the input is a number
		window.alert("Please enter a valid number");
	}
	else if(guess < minNum || guess > maxNum){
		window.alert("Please enter a valid number");
	}
	else{
		attempts++;
		if(guess < answer){
			window.alert("Too Low");
		}
		else if(guess > answer){
			window.alert("Too High");
		}
		else(
			window.alert(`Correct,it took you ${attemps} times`);
			running = false
		)
	}
