for...in Loop (ऑब्जेक्ट के लिए)

हिंदी व्याख्या: for...in loop ऑब्जेक्ट की keys (properties) पर लूप चलाने के लिए इस्तेमाल होता है।

English Explanation: for...in is used to loop through the properties (keys) of an object.

Example:-

let student = { name: "Rahul", age: 20, city: "Delhi" };

for (let key in student)

{

document.write(key + " = " + student[key] + "<br>");

}

Output:-

age = 20

city = Delhi

बिना for...in के:-

let student = {

name: "Rahul",

age: 20,

city: "Delhi"

};

document.write(student.name + "<br>");

document.write(student.age + "<br>");

document.write(student.city);

Output:-

Rahul
20
Delhi
