iterate over keys in object javascript code example

Example 1: javascript loop through object

Object.entries(obj).forEach(
    ([key, value]) => console.log(key, value)
);

Example 2: iterate key value object javascript

'use strict';
// ECMAScript 2017
const object = {'a': 1, 'b': 2, 'c' : 3};
for (const [key, value] of Object.entries(object)) {
  console.log(key, value);
}

Example 3: javascript iterate object key values

Object.entries(obj).forEach(([key, value]) => {
	console.log(key, value);
});

Example 4: javascript iterate over object keys and values

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: going through every attributes of an object javascript

let a = {x: 200, y: 1}
let attributes = Object.keys(a)
console.log(attributes)
//output: ["x", "y"]
