js loop object key code example

Example 1: iterate object javascript

let obj = {
	key1: "value1",
	key2: "value2",
	key3: "value3",
	key4: "value4",
}
Object.entries(obj).forEach(([key, value]) => {
	console.log(key, value);
});

Example 2: loop over keys in object javascript

Object.keys(obj).forEach(function(key) {
  console.log(key, obj[key]);
});

Example 3: javascript iterate object key values

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

Example 4: 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

Example 5: loop through object javascript

for (var property in object) {
  if (object.hasOwnProperty(property)) {
    // Do things here
  }
}

Example 6: javascript loop through object values

var myObj = {foo: "bar", baz: "baz"};
Object.values(myObj).map((val) => {
console.log(val);
})
// "bar" "baz"
