循环的几种用法

const todos = [
    { id: 1, text: '第一个数组 Buy groceries', completed: false },
    { id: 2, text: '第二个数组 Finish homework', completed: false },
    { id: 3, text: '第三个数组 Cook dinner', completed: false },
    { id: 4, text: '第四个数组 Wash car', completed: false },
];

console.log(todos.length);

//for
for (let i = 0; i < todos.length; i++) {
    console.log(`for ${i}`);
    console.log(`todos` + todos[i].id + ` - ` + todos[i].text)
}

//while
let x = 10
while (x < 14) {
    console.log(`loop ${x}`);
    x++;
}

//for of
for (let todo of todos) {
    console.log(todo.text)
}
