We could just call populateTodoList() to update the view (to avoid maintaining two sets of code to change view).

});

const trashIcon = document.createElement("i");
trashIcon.className = "fa fa-trash ms-2";
trashIcon.style.cursor = "pointer";
trashIcon.addEventListener("click", () => {
todos.splice(todos.indexOf(todo), 1);

For better performance (i.e., without the need to search for todo in the array), we could make available the index of the current todo at line 11 as

   todos.forEach((todo, index) => {

populateTodoList(todos);
});

span.appendChild(checkIcon);
span.appendChild(trashIcon);
li.appendChild(span);
list.appendChild(li);
});
}

populateTodoList(todos);

// This function will take the value of the input field and add it as a new todo to the bottom of the todo list. These new todos will need the completed and delete buttons adding like normal.
// Add new todo
function addNewTodo(event) {
// The code below prevents the page from refreshing when we click the 'Add Todo' button.
event.preventDefault();
// Write your code here... and remember to reset the input field to be blank after creating a todo!
const input = document.querySelector("input[type='text']");
const task = input.value.trim();
if (task !== "") {
todos.push({ task, completed: false });
input.value = "";
populateTodoList(todos);
}
}

// Advanced challenge: Write a fucntion that checks the todos in the todo list and deletes the completed ones (we can check which ones are completed by seeing if they have the line-through styling applied or not).
function deleteAllCompletedTodos() {
// Write your code here...
}
document.querySelector("form").addEventListener("submit", addNewTodo);

// Remove all completed
document
.getElementById("remove-all-completed")
.addEventListener("click", () => {
todos = todos.filter((todo) => !todo.completed);
populateTodoList(todos);
});
