// Using an id to get the element
const textarea = document.getElementById('area');
function randomNumber(max) {
return Math.floor(Math.random() * max + 1);
}
const list = []
while(list.length < 25 ){
let nbr = randomNumber(25)
if(!list.find(el => el === nbr))
list.push(nbr)
}
// Set the value to the list
textarea.value = list;

<textarea name="" id="area" cols="30" rows="10"></textarea>
