iterate object keys javascript 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: iterate key value object javascript

'use strict';
// ECMAScript 2017
const object = {'a': 1, 'b': 2, 'c' : 3};
for (const [key, value] of Object.entries(object)) {
  console.log(key, value);
}

Example 3: javascript loop through object

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

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

Example 4: javascript iterate object key values

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

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

Example 6: loop through object javascript

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