for each element in object javascript code example

Example 1: foreach object javascript

const students = {
  adam: {age: 20},
  kevin: {age: 22},
};

Object.entries(students).forEach(student => {
  // key: student[0]
  // value: student[1]
  console.log(`Student: ${student[0]} is ${student[1].age} years old`);
});
/* Output:
Student: adam is 20 years old
Student: kevin is 22 years old
*/

Example 2: javascript loop through object

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

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

Example 3: foreach object javascript

/* Answer to: "foreach object javascript" */

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.

Example 4: foreach object js

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 5: for each element in object

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

//
//	Visit non-inherited enumerable keys
//
Object.keys(obj).forEach(function(key) {

  console.log(key, obj[key]);

});

Example 6: foreach object javascript

const obj = {
  a: "aa",
  b: "bb",
  c: "cc",
};
//This for loop will loop through all keys in the object.
// You can get the value by calling the key on the object with "[]"
for(let key in obj) {
  console.log(key);
  console.log(obj[key]);
}

//This will return the following:
// a
// aa
// b
// bb
// c
// cc
