Reading the code

Question

I have couple line of code, can someone help me explain what just happened. It's a JavaScript code (not the first 3 line):

const todos = document.querySelectorAll('.todoItem');
const completedTodos = document.querySelector('.completed');
const completedWrapper = document.querySelector('.completedTodoWrapper');

todos.forEach(todo => todo.addEventListener('click', (event) => {
let completedTodo = document.createElement('li');
let todoContent = document.createTextNode(todo.textContent);
completedTodo.appendChild(todoContent);
completedWrapper.insertBefore(completedTodo, completedTodos);
todo.remove();
}));

Thank you
