I want to create a todo list using array and loop and display the list in div container. I am able to display the list but it is muliplying the same list stored and is displayed.

<body>
    <p class="title"> Todo List </p>
    <input type="text" class="js-input-todo" placeholder="Todo name">
    <button type="submit" class="js-btn-todo" onclick="handleAddTodo()">Add</button>

    <div class="todo-list"></div>

 <script src="script/11-arrays-loop.js"></script>
</body>

//script 

let names = []

let todoListHTML = ''

function handleAddTodo(){
  const todo_input = document.querySelector('.js-input-todo');
  const todoValue = todo_input.value
  const result = document.querySelector('.todo-list');
 
  names.push(todoValue);
  for(let i = 0; i <  names.length ; i++){
   let todoName = names[i]
   const html = `<p>${todoName} </p>`
   todoListHTML = html;
   result.innerHTML +=todoListHTML;
   
   todo_input.value = '';
  }
  
  

}
