如何将对象数组转换为JSON（并返回）？

Question

For simplicity's sake, I have a JavaScript Array of car objects as below (one example):

var car = {
    "color": "red",
    "fuelType": "diesel"
}

I'd like to store this array of objects in the user's localStorage and be able to retrieve and add/delete to it.

Here is some example code that I cannot seem to get right.

addCar(car);

function getCars() {
    var cars = [];
    if (localStorage['cars']) {
        cars = localStorage['cars'];
    }

    return cars;
}

function addCar(car) {
    var cars = getCars();
    cars.push(car);
    localStorage['cars'] = cars;
}

How can I convert an array of objects into JSON (and return it)? localStorage only allows for the storage of Strings. I need to convert the array of objects into a JSON format, but I am not sure how.

据我所知，本地存储仅支持字符串，因此您必须使用JSON.stringify()和JSON.parse()来获取和获取数据。
