javascript associative object foreach
The Object.entries() method returns an array of a given object's own enumerable string-keyed property [key, value] pairs,
const object1 = {
a: 'somestring',
b: 42
};
for (const [key, value] of Object.entries(object1)) {
console.log(`${key}: ${value}`);
}
// expected output:
// "a: somestring"
// "b: 42"
// order is not guaranteed
