const students = {
  adam: {age: 20},

};

Object.entries(students).forEach(student => {
  // key: student[0]
  // value: student[1]
  console.log(`Student: ${student[0]} is ${student[1].age} years old`);
});

const games = {
  "Fifa": "232",
  "Minecraft": "476"
  "Call of Duty": "182"
};

Object.keys(games).forEach((item, index, array) => {
  let msg = `There is a game called ${item} and it has sold ${games[item]} million copies.`;
  console.log(msg);
});

/*
  The foreach statement can be used in many ways and with object can make
  development a lot easier.
  
  A link for for more information on this can be found below and in the source:

  key: "value",
  name: "lauren",
  email: "[email protected]",
  age: 30
};

// Object.keys returns an array of the keys
// for the object passed in as an argument.

Object.keys(list).forEach(val => {
  let key = val;
  let value = list[val];
  console.log(`${key} : ${value}`);
});

// Returns:
// "key : value"
// "name : lauren";
// "email : [email protected]"
// "age : 30"

  a: 'somestring',

};
for (let [key, value] of Object.entries(object1)) {
  console.log(`${key}: ${value}`);
}
// expected output:
// "a: somestring"
// "b: 42"
// order is not guaranteed

                                    function logArrayElements(element, index, array) {
  console.log('a[' + index + '] = ' + element)
}

// Notice that index 2 is skipped, since there is no item at
// that position in the array...
[2, 5, , 9].forEach(logArrayElements)
// logs:
// a[0] = 2
// a[1] = 5
// a[3] = 9
