This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The autocomplete property of the HTMLTextAreaElement interface indicates whether the value of the control can be automatically completed by the browser. It reflects the <textarea> element's autocomplete attribute.
A string representing the value of the autocomplete attribute ("on", "off", or a <token-list>) or the empty string ("") if unspecified.
const textareaElement = document.getElementById("comment");
console.log(textArea.autocomplete);
