Рендеринг массива при загрузке страницы в Javascript

У меня есть массив, который я хотел бы отображать при загрузке страницы. В моем коде ниже он срабатывает в блоке кода, когда я нажимаю новый элемент массива.

Есть ли способ взять часть кода, в котором я перебираю массив и помещаю его в функцию, и вызываю эту функцию при загрузке страницы, а затем вызываю ее всякий раз, когда я нажимаю новый элемент массива.

Это HTML-код:

<h1>Todos</h1>
 <form action = "" id = "addTodo">
 <input type = "text" name = "inputTodo" placeholder = "Insert new todo">
 <button>Add Todo</button> 
 </form>
 <input id = "search-todo" type = "text" placeholder = "Search todo">
 <button id = "reset-search" type = "reset" value = "reset" onclick = "window.location.reload()">New search</button>

 <div id = "todos"></div>
 <script src = "js/index.js"></script>   

и это мой код js:

const todos = [{
  text: 'Order airline tickets',
  completed: false
},{
  text: 'Vaccine appointment',
  completed: true
}, {
  text: 'Order Visa',
  completed: true
}, {
  text: 'Book hotell',
  completed: false
}, {
  text: 'Book taxi to airport',
  completed: true
}]

//Insert new todo
document.querySelector('#addTodo').addEventListener('submit', function (e) {
    e.preventDefault()
    newTodo = document.querySelector('[name = "inputTodo"]').value;
    todos.push({text: newTodo, completed: false});
    console.info(todos)

    //show the whole array
todos.forEach(function (todo,) {
  const p = document.createElement('p')
  p.textContent = todo.text
  document.querySelector('body').appendChild(p)

  let radio_button_true = document.createElement("INPUT") // Creating input tag for true button
  radio_button_true.setAttribute("type", "radio")

  let radio_button_false = document.createElement("INPUT") // Creating input tag for false button
  radio_button_false.setAttribute("type", "radio")

//create variable to generate random id for radiobutton
  const id = Math.random().toString(36)

  radio_button_true.setAttribute("name", id)
  radio_button_false.setAttribute("name", id)

  //Switch loop over the completed
  switch (todo.completed) {
    case true:
      radio_button_true.setAttribute("checked", "true") // Mark true button as checked
      break
    case false:
      radio_button_false.setAttribute("checked", "true") // Mark false button as checked
      break
    default:
      break
  }

  document.body.appendChild(radio_button_true) // Appending true radio button to body

  let radio_button_true_node = document.createElement("span")
  let radio_button_true_text = document.createTextNode("true") // Creating span text with true
  radio_button_true_node.appendChild(radio_button_true_text)
  document.body.appendChild(radio_button_true_node)

  document.body.appendChild(radio_button_false) // Appending false radio button to body

  let radio_button_false_node = document.createElement("span")
  let radio_button_false_text = document.createTextNode("false") // Creating span text with false
  radio_button_false_node.appendChild(radio_button_false_text)
  document.body.appendChild(radio_button_false_node)

})

const notDone = todos.filter(function (todo) {
  return !todo.completed
})

const summary = document.createElement('h2')
summary.textContent = `You have a total of ${notDone.length} todos pending`
document.querySelector('#addTodo').appendChild(summary)

})

//contains the search text
const filters = {
  searchText: ''
}

//Function that takes in the notes object and the search text as parameters
const renderTodos = function (todos, filters) {

  //use filter method for the title search string and save it to filters variable
    const filteredTodos = todos.filter(function (todo) {
        return todo.text.toLowerCase().includes(filters.searchText.toLowerCase())
    })

    const notDone = filteredTodos.filter(function (todo) {
      return !todo.completed
    })

    //Empty the div containg the result, this has to be between filter and the display of the result
    document.querySelector('#todos').innerHTML = ''

    const summary = document.createElement('h4')
    summary.textContent = `You found ${notDone.length} hit${notDone.length !== 1 ? 's' : ''} on this search that is not complete`
    document.querySelector('#todos').appendChild(summary)



    //loop through note object, create a p tag for the title searched and append to the div
    filteredTodos.forEach(function (todo) {
      const noteEl = document.createElement('p');
      noteEl.textContent = todo.text;
      if (!todo.completed) {
          noteEl.style.backgroundColor = "yellow";
      }
      document.querySelector('#todos').appendChild(noteEl);
  })
    elem = document.createElement("hr")
    document.querySelector('#todos').appendChild(elem)
}

document.querySelector('#search-todo').addEventListener('input', function (e) {
  filters.searchText = e.target.value
  renderTodos(todos, filters)
})

Благодарность :)
