how to loop through key value pair in javascript code example

Example 1: foreach key value javascript

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 2: for key value in object javascript

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