javascript function to return object returns [object Object]
提问by kilojoules
The intended output of my function is {"name": "bob", "number": 1}, but it returns [object Object]. How can I achieve the desired output?

return {"name": "bob", "number": 1};
}
myfunc();

Haha this seems to be a simple misunderstanding. You are returning the object, but the toString()method for an object is [object Object]and it's being implicitly called by the freecodecamp console.
哈哈，这似乎是一个简单的误会。您正在返回对象，但对象的toString()方法是[object Object]并且它被 freecodecamp 控制台隐式调用。
var o = {}; // o is an Object
o.toString(); // returns [object Object]
You can easily verify you actually are returning an object using your own code:
您可以使用自己的代码轻松验证您实际上是在返回一个对象：
function myfunc() {
return {"name": "bob", "number": 1};
}
var myobj = myfunc();
console.log(myobj.name, myobj.number); // logs "bob 1"回答by aliasm2k
If you try console.log(ob.name)it should display bob
如果你尝试console.log(ob.name)它应该显示bob
{}in JS is a shorthand for an object. You can convert your object to string using the toString()method.
{}in JS 是对象的简写。您可以使用该toString()方法将对象转换为字符串。
