One Google away.

<script language="javascript" type="text/javascript">
<!--
function imposeMaxLength(Object, MaxLen)
{
  return (Object.value.length <= MaxLen);
}
-->
</script>

Implementation:
<textarea name="myName" onkeypress="return imposeMaxLength(this, 50);" ></textarea> 

EDIT:

Code that doesn’t freeze text:

<script type="text/javascript">

/***********************************************

function imposeMaxLength(obj) {
        const mlength = obj.getAttribute ? parseInt(obj.getAttribute("maxlength")) : ""
        if (obj.getAttribute && obj.value.length > mlength) {
            obj.value = obj.value.substring(0, mlength)
        }
        obj.value = obj.value.trim()
    }

</script>

<textarea maxlength="40" onkeyup="return imposeMaxLength(this)"></textarea>
