logic problem in javascript - 2 requirements array/object

const data = [
    { name: "Table", color: ["green", "red", "blue"], price: 300 },
    { name: "Desk", color: ["white", "yellow", "grey"], price: 300 },
    { name: "Desk", color: ["black", "pink", "green"], price: 500 },
];

Hello, I'm trying to code buy-list in objects, but I met logic problem here because for example, there can be same object (called Desk) but with different array (color) for different price.

How can I grab info about price if my script will meet 2 requirements - it will be Desk, color will be black for example, and result needs to be 500 using .find() function returns 1st object (in this case: { name: "Desk", color: ["white", "yellow", "grey"], price: 300 })

Please help :D Greetings.

You could take Array#find with Array#includes for the wanted color.

As result you get either an item or undefined, if the request does not match.

const
    data = [{ name: "Table", color: ["green", "red", "blue"], price: 300 }, { name: "Desk", color: ["white", "yellow", "grey"], price: 300 }, { name: "Desk", color: ["black", "pink", "green"], price: 500 }],
    request = { name: 'Desk', color: 'black' },
    result = data.find(({ name, color }) =>
        name === request.name &&
        color.includes(request.color)
    );

console.log(result);

Given just the information your data has you either need to come up with a cumbersome approach like trying to find the color as well, or make sure to include a unique identifier like a SKU into your objects.
