<script>
    let truncateme = document.querySelectorAll("[data-truncate]");
    truncateme.forEach(truncate);
    function turnecate(item) {
        var value = item.getAttribute('data-truncate');
        var txt = item.textContent;
        if (txt.length > value) {
            var txt1 = item.textContent.substring(0,value) + '...';
            console.log(txt1)
        }else{
            console.log(txt)
        }
        
    }


</script>

`data-truncate` is a string, even if you put a numeric value into it. To use it with `substring`, you'll need to [parse it into a number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/parseInt). In addition, your function name is misspelled and doesn't match what you're passing to `forEach`. — Etheryte, Jun 17 '22 at 14:08
your code works fine when you correct the mispelling of the function declaration. `function turnecate(item) {...` should be `function truncate(item) {...`. — Dave Pritlove, Jun 17 '22 at 14:11
