我想在你點擊的時候做一個系統：
{點擊前=硬幣：0}
{點擊后=硬幣：1}
使用.js。
add(x);
remove(x);
我想開店：
function e() {
var demo = document.getElementById('demo').innerHTML=add(1);
}
和
<button onclick="e()">get 1 coin</button>
要做到這一點：
function e() {
var demo = document.getElementById('demo').innerHTML = "Coins: 1";
}<!DOCTYPE>
<html>
<body>
<p id='demo'>Coins: 0</p>
<button onclick="e()">get 1 coin(plz edit this code)</button>
</body>

<body>

<!-- get web script form javascript -->
<script>
let counter =0;
function e() {
counter ;
var demo = document.getElementById('demo').innerHTML=`Coins: ${counter}`;
}
