mdn object.entries code example

Example 1: javascript object entries

// Object Entries returns object as Array of [key,value] Array
const object1 = {
  a: 'somestring',
  b: 42
}
Object.entries(object1) // Array(2) [["a", "something"], ["b", 42]]
  .forEach(([key, value]) => console.log(`${key}: ${value}`))
// "a: somestring"
// "b: 42"

Example 2: object iterate in javascript

for (let [key, value] of Object.entries(yourobject)) {
    console.log(key, value);
}

Example 3: object iterate in javascript

for (let key in yourobject) {
  console.log(key, yourobject[key]);
}

Example 4: object values

const object1 = {
  a: 'somestring',
  b: 42,
  c: false
};

console.log(Object.values(object1));

// expected output: Array ["somestring", 42, false]

Example 5: js object entries

var obj = { foo: 'bar', baz: 42 };
console.log(Object.entries(obj)); // [ ['foo', 'bar'], ['baz', 42] ]

// objeto array-like
var obj = { 0: 'a', 1: 'b', 2: 'c' };
console.log(Object.entries(obj)); // [ ['0', 'a'], ['1', 'b'], ['2', 'c'] ]

Object.entries(obj).forEach(([key, value]) => {
    console.log(key + ' ' + value); // "a 5", "b 7", "c 9"
});

Example 6: javascript iterate object

for (let key in yourobject) {
   if (yourobject.hasOwnProperty(key)) {
      console.log(key, yourobject[key]);
   }
}
