列表迭代不能用作函数参数

如何解决列表迭代不能用作函数参数

我试图遍历一个列表，并将每个值传递给一个函数。如果我手动键入每个列表值，该功能将正常工作。我使用console.log来确保cars [x]返回正确的值。问题在varworthALook行的末尾。

我是JS的新手，我试图了解正在发生的事情。

function prequal(car){
    if (car.mileage > 100000){
        return false;
    } else if (car.year > 1960){
        return false;
    }
    return true;
}

let taxi = {
    make: "Webville Motors",model: "Taxi",year: 1955,color: "yellow",passengers: 4,convertible: false,mileage: 281341
}

let cadi = {
    make: "GM",model: "Cadillac",color: "tan",passengers: 5,mileage: 12892
}

let fiat = {
    make: "Fiat",model: "500",year: 1977,color: "Medium Blue",passgengers: 2,mileage: 88000
}

let chevy = {
    make: "Chevrolet",model: "Bel Air",year: 1957,color: "red",mileage: 1021
}
cars = ["taxi","cadi","fiat","chevy"]


for ( x=0; x < cars.length; x++){
    console.log(cars[x]);
    var worthALook = prequal(cars[x]);

    if (worthALook){
        console.log("Your gotta check out this " + cars[x]);
    }else {
        console.log("You should really pass on the " + cars[x]);
    }
}
