在陣列中查詢物件

使用 find()

const inventory = [
    {name: 'apples', quantity: 2},
    {name: 'bananas', quantity: 0},
    {name: 'cherries', quantity: 5}
];

function findCherries(fruit) { 
    return fruit.name === 'cherries';
}

inventory.find(findCherries); // { name: 'cherries', quantity: 5 }

/* OR */

inventory.find(e => e.name === 'apples'); // { name: 'apples', quantity: 2 }
