</button>
<p id="gfg"></p>
<script>
var el_down = document.getElementById("gfg");
function gfg_Run() {
const isIOS = ["iPad Simulator",
"iPhone Simulator",
"iPod Simulator",
"iPad", "iPhone",
"iPod"]
.indexOf(navigator.platform) !== -1;
el_down.innerHTML = isIOS;
}

"iPod"];
if (!!navigator.platform) {
while (Devices.length) {
if (navigator.platform === Devices.pop()) {
return true;
}
}
}
