过滤数组中所需的项目并显示它们

Question

我想使用数组方法在菜单中找到最便宜的食物，并在控制台中显示价格高于 10 的食物以及名称和 ID。 谢谢您的帮助。

let menu = [
    { id: 1, name: "Soda", price: 3.12, size: "4oz", type: "Drink" },
    { id: 2, name: "Beer", price: 6.50, size: "8oz", type: "Drink" },
    { id: 3, name: "Margarita", price: 12.99, size: "12oz", type: "Drink" },
    { id: 4, name: "Pizza", price: 25.10, size: "60oz", type: "Food" },
    { id: 5, name: "Kebab", price: 31.48, size: "42oz", type: "Food" },
    { id: 6, name: "Berger", price: 23.83, size: "99oz", type: "Food" },
];

它不是很复杂，只需使用 FOR 循环读取数组并使用 IF 过滤数据.. :)

var menu = [
    { id: 1, name: "Soda", price: 3.12, size: "4oz", type: "Drink" },
    { id: 2, name: "Beer", price: 6.50, size: "8oz", type: "Drink" },
    { id: 3, name: "Margarita", price: 12.99, size: "12oz", type: "Drink" },
    { id: 4, name: "Pizza", price: 25.10, size: "60oz", type: "Food" },
    { id: 5, name: "Kebab", price: 31.48, size: "42oz", type: "Food" },
    { id: 6, name: "Berger", price: 23.83, size: "99oz", type: "Food" },
];

var menu2 = [];  // creates a new array to hold the results 
for(var i = 0; menu[i]; i++){
    if(menu[i].price > 10) menu2[menu2.length] = menu[i]; // If an item has a price greater than 10 then I copy it to the new menu 
}

console.log(menu2); // Display the new menu with the filtered data in the console
