Why does it disappear?
In the code bellow, i programmed an app where you can send messages. But when i click the send button, the whole entire page disappears. Can someone please explain? I and chatgpt have no clue. https://sololearn.com/compiler-playground/W6bfbvoSqV8h/?ref=app

don't use form.
as Lisa said, clicking on a button nested inside form tags will default to a submit action and it will refresh your page resulting in a blank page in Sololearn.
you can test it by just only writing this in your html tab:
<form><button>click me</button></form>
clicking the button will clear your page. The button will disappear...
clear your js tab and copy-paste this on your html tab:
<!DOCTYPE html>
<html>
<head>
<title>Message For Yourself</title>
</head>
<body>
<table id="list"></table>
<input type="text" id="text">
<button onclick="submit()">/\</button>
<script>
const input = document.getElementById("text");
function submit() {
let text = input.value;
if(text) {
input.value = "";
let table = document.getElementById("list");
let row = table.insertRow(-1);
let cell1 = row.insertCell(0);
cell1.innerHTML = text;
}
}
</script>
</body>
</html>

Per default, some browsers clear the page when the submit event is triggered.

Does it disappear on your other IDE/Computer/Browser? Or only on Sololearn?
I'm pretty sure Sololearn has limited functions and sending a message wouldn't be something the code playground can do.
