String.fromCharCode(n1, n2, ..., nX)
Parameters:
n1, n2, nX : required. One or more Unicode values to be converted.
<p>Convert 65 to a string:</p>
<p id="demo"></p>
<script>
let text = String.fromCharCode(65);
document.getElementById("demo").innerHTML = text;
</script>
console.log(String.fromCharCode(189, 43, 190, 61));
// Expected output: "½+¾="
String.fromCharCode(65, 66, 67); // returns "ABC"
String.fromCharCode(0x2014); // returns "—"
String.fromCharCode(0x12014); // also returns "—"; the digit 1 is truncated and ignored
String.fromCharCode(8212); // also returns "—"; 8212 is the decimal form of 0x2014
example: chek if a string ends with "...".
