js loop through keys of object code example

Example 1: loop over keys in object javascript

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

Example 2: 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
