我如何打印javascript对象/变量？

Question

**** NOT A DUPE _重复的指JSON只有****

我希望避免这种情况时登录JS瓦尔控制台：

var user = { 
    first: 'Jack', 
    last: 'Green', 
    age: 54 
}; 

// plain console log 
console.log(user); 

// or with interpolation: 
console.log(`User: ${user}`); 

这结束了，如：

{ prop1: 'value1', prop2: 2 } 

User: [Object object]

更改上面的例子：

var user = { 
    first: 'Jack', 
    last: 'Green', 
    age: 54 
}; 

// plain console log 
console.log(JSON.stringify(user, undefined, 2)); 

// or with interpolation: 
console.log(`User: ${JSON.stringify(user, undefined, 2)}`); 

，现在我们得到的漂亮的输出：

{ 
    "first": "Jack", 
    "last": "Green", 
    "age": 54 
} 

User: { 
    "first": "Jack", 
    "last": "Green", 
    "age": 54 
}
