英文:
Create an object “car” and have one of its properties display a string
问题
-
定义一个名为
car的变量，是一个带有以下属性的对象：-
model为'Nissan' -
color为'Blue' -
numWheels是一个轮子的数量，值为4
-
-
这个对象还应该有以下方法：
- 方法
drive，返回'Vroom!'
- 方法
你尝试的代码：
const car = {
model: 'Nissan',
color: 'Blue',
numWheels: 4,
drive: function() {
return 'Vroom!';
}
}
console.log(car);
你得到的结果：
{
model: 'Nissan',
color: 'Blue',
numWheels: 4,
drive: [Function: drive]
}
我已将 "console.log ('Vroom!')" 更改为 "return 'Vroom!'"，你得到了需要的结果。
英文:
-
Define a variable
car, an Object with the following properties:-
modelof’Nissan’ -
colorof’Blue’ -
numWheels, a number of wheels. Value is4
-
-
The object should also have the following method:
- Method
drivethat returns’Vroom!’
- Method
What I tried:
const car = {
model: 'Nissan',
color: 'Blue',
numwheels: 4,
drive: function() {
return'Vroom!'
},
}
console.log (car)
What I got:
{
model: 'Nissan',
color: 'Blue',
numwheels: 4,
drive: [Function: drive]
}
I have changed “console.log (‘Vroom!)”
To “return ‘Vroom!’”
And I get the result I need

- Method
drivethat returnsVroom!
在你的代码中，你的 drive() 方法将 Vroom! 记录到控制台，而不是将其作为函数的返回值。将 console.log('Vroom!') 更改为 return 'Vroom!'，并使用 console.log(car.drive()) 而不是 console.log(car)。你的完整代码应该类似于以下内容：
const car = {
model: 'Nissan',
color: 'Blue',
numwheels: 4,
drive: function() {
return 'Vroom!';
},
}
console.log(car.drive());
英文:
> - Method drive that returns Vroom!
In your code, your drive() method is logging Vroom! to the console, not returning it as the value of the function. Change console.log('Vroom!') to return 'Vroom!' and use console.log(car.drive()) instead of console.log(car). Your complete code should look something like this:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
const car = {
model: 'Nissan',
color: 'Blue',
numwheels: 4,
drive: function() {
return 'Vroom!';
},
}
console.log (car.drive());
<!-- end snippet -->
