I have a div that fills with the view count of the page. What I want to is make a request to my server to get the view count and then render that on the page. However, since the page loads before the request responds, the text shown is [Object Promise].
The code in my <script> tag is:
<script>
document.getElementById("viewcount").innerHTML = await fetch("https://mywebsite.com/peripherals/viewcount")
.then(function (response) {
return response.json();
}).then(function (json) {
return json.count
}).catch(function (error) {
console.log("Error: " + error);
});
</script>
How can I delay the rendering of the viewcount until a response is returned?

This would happen if you would not use await.
When you add await, you'll get an error, because it can only be used (at the time of writing) within an async function, so wrap it:
(async function () {
document.getElementById("viewcount").innerHTML = await fetch(/* ...etc */);
})();
You could use await all the way:
(async function () {
try {
const response = await fetch("https://mywebsite.com/peripherals/viewcount");
const {count} = await response.json();
document.getElementById("viewcount").innerHTML = count;
} catch (error) {
console.log("Error: " + error);
}
})();
