Keyup funciona solo cuando se hace clic en el botón 'enviar'

Quiero aplicar colores al campo de entrada mientras escribo en él, sin embargo, se aplica solo después de hacer clic en el botón "enviar".

 const form=document.querySelector('form'); const submit=document.querySelector('submit'); const pattern=/^[a-zA-Z]{6,12}$/; const feedback=document.querySelector('.feedback'); form.addEventListener('submit', (e)=>{ e.preventDefault(); if(pattern.test(form.username.value)){ feedback.textContent='Nice :)'; }else{feedback.textContent='Too Sad :('} }) form.username.addEventListener('keyup', (e)=>{ if(pattern.test(e.target.value)){ form.username.setAttribute('class', 'success')} else{form.username.setAttribute('class', 'error')} })
