Did you abandon your previous thread?

I'm assuming (not "suing"!) you mean JavaScript not POstScript here, too.

JavaScript has no sleep. The idea of blocking code in something built for the UI is an anathema. However, you can fake it.

The following works. It wraps the setTimeout in a promise, then uses await to block on it. 

<html>
<head><title>Not a great general purpose programming environment</title></head>
<body>
<script>
ShowLine("You can't always get what you want.");

function sleep(ms = 0) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

async function ShowLine(input) {
  for (let i = 0; i < input.length; i++) {
    await sleep(250);
    document.write(input[i]);
  };
}
</script>
</body>
</html>

 

It seems to me you're really needing something else to do your programming with. (But you don't provide much detail to work with.)
