setInterval(() =>
const textarea = doc.getElementById(‘my-textarea’);
const textual content = textarea.worth;
textarea.worth += ‘Hiya, World!’;
detectWordWrap(textarea);
, 1000);
“`
By incorporating the customized operate into the appliance, we are able to successfully monitor and reply to adjustments in phrase wrap conduct, making certain a seamless and responsive person expertise.
