array[0].text

But you should change the structure of "array"... For the moment you have an array with only one element, and it's an object.

Either you want to handle an array of objects, or you want to only have one element, in that case you use an object:

const case1 = [
  {
    text: "hello",
    number: 23,
  },
  {
    text: "hello2",
    number: 2345,
  }
];

const case2 = {
  text: "hello",
  number: 23,
}

Your this code needs to be changed to

newText.innerText = `${array[0].text}`;
