This feature is well established and works across many devices and browser versions. Its been available across browsers since July 2015.
The validationMessage read-only property of the HTMLTextAreaElement interface returns a string representing a localized message that describes the validation constraints that the <textarea> control does not satisfy (if any). This is the empty string if the control is not a candidate for constraint validation (HTMLTextAreaElement.willValidate is false), or it satisfies its constraints.
If the <textarea> element is a candidate for constraint validation (willValidate is true) and the constraints are not met (the HTMLTextAreaElement.validity object's valid property is false), the value is the error message that would be shown to the user during validation.
A string.
const textarea = document.getElementById("myTextArea");
const errorMessage = textarea.validationMessage;
