javascript each object code example

Example 1: javascript loop through object example

var person={
 	first_name:"johnny",
  	last_name: "johnson",
	phone:"703-3424-1111"
};
for (var property in person) {
  	console.log(property,":",person[property]);
}

Example 2: foreach object javascript

const obj = {
  name: 'Jean-Luc Picard',
  rank: 'Captain'
};

// Prints "name Jean-Luc Picard" followed by "rank Captain"
Object.entries(obj).forEach(entry => {
  const [key, value] = entry;
  console.log(key, value);
});

Example 3: 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 4: 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

Example 5: js object for each

const obj = {
  a: 1, 
  b: 2, 
  c: 3
};
    
for (let key in obj) {
  console.log(key + " = " + obj[key]);
}
// Ausgabe:
// "a = 1"
// "b = 2"
// "c = 3"

Example 6: for each of object

Object.keys(object).map(function(objectKey, index) {
    var value = object[objectKey];
    console.log(value);
});
