Question

我对NodeJS很新，所以这个任务是我开始接受NodeJS培训的第一步。我遇到了一个我根本不懂的问题。一个简单的帮助对我来说是伟大的。

这是我的代码

var rect = {
perimeter: function (x,y) {
       return (2*(x+y));
},
area: function (x,y) {
        return (x*y);
}
};

function solveRect(l,b) {
console.log("Solving for rectangle with l = " + l + " and b = " + b);

if (l < 0 || b < 0) {
    console.log("Rectangle dimensions should be greater than zero:  l = " + l + ",  and b = " + b);
}
else {
console.log("The area of a rectangle of dimensions length = " + l + " and breadth = " + b + " is " + rect.area(l,b));
console.log("The perimeter of a rectangle of dimensions length = " + l + " and breadth = " + b + " is " + rect.perimeter(l,b));
}
}

solveRect(2,4);
solveRect(3,5);
solveRect(-3,5);

我遇到的错误是

console.log("The area of a rectangle of dimensions length = " + l + " and 
                                                                        ^^^^^^
