i noticed some people asking about whether objects are iterable or not?

ANSWER
JavaScript objects are not considered iterable by default. However, starting from ECMAScript 2015 (ES6), JavaScript introduced the concept of iterable objects and the Symbol.iterator protocol. Objects can be made iterable by implementing this protocol.

so the for in method works only on iterable objects

By default, plain objects (objects created using object literals {}) are not iterable. They don't have the necessary Symbol.iterator method, so you cannot use a for...of loop directly on them.

i think we can iterate in bojects with for in loop

const obj1 = {
name: "X",
surname: "Y",
age: 22,
};
for (let keys in obj1){
console.log(keys);
}

it will print the keys as follows:

name
surname
age

works in chrome browser
do let me update if it is true or not

Object we can not be iteratable.
