iterate through an object code example

Example 1: javascript loop through object

Object.entries(obj).forEach(
    ([key, value]) => console.log(key, value)
);

Example 2: javascript iterate over object

var obj = { first: "John", last: "Doe" };

});

	phone:"703-3424-1111"
};
for (var property in person) {
  	console.log(property,":",person[property]);
}

Example 5: javascript iterate over object keys and values

const object1 = {
  a: 'somestring',
  b: 42
};

for (let [key, value] of Object.entries(object1)) {
  console.log(`${key}: ${value}`);
}

// expected output:
// "a: somestring"
// "b: 42"
// order is not guaranteed
