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"

foreach key value javascript

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

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"
});

js entries

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
