javascript - JSON.stringify() 在值上带有单引号，在键上没有引号

Question

在 Javascript 中:打印一个 json 对象

var myObject = new Object;
myObject.type = "Fiat";
myObject.model = "500";
myObject.color = "White";

以下格式

{ type: 'Fiat', model: '500', color: 'White' }

在 console.log 中。
但实际结果

{"type":"Fiat","model":"500","color":"White"}

挑战在这里:
hackerrank print JSON object

function printObjectProperty(myObject) {
  //Write your code here
console.log(JSON.stringify(myObject)); 
 //OR
console.log("{ type: '"+myObject.type+"', model: '"+myObject.model+"', color: '"+myObject.color+"'}"); //OR THERE COULD BE A BETTER GENERIC SOLUTION
}

您可以使用以下代码:

var json = JSON.stringify(myObject);  // {"type":"Fiat","model":"500","color":"White"}
console.log(json);
var unquoted = json.replace(/"([^"]+)":/g, '$1:');
console.log(unquoted);  // {type:"Fiat",model:"500",color:"White"}
var result = unquoted.replaceAll("\"", "'");
console.log(result); // {type:'Fiat',model:'500',color:'White'}
