The difference is: Object.values() only returns enumerable property values, while Object.fromEntries() returns all properties whether enumerable or not.

Similar methods and differences between object to array and array to object

Object to array

Similar methods: Use the Object.values() method, which returns an array containing all enumerable property values ​​of the object.

Code example:

const obj = {
  name: "John",
  age: 30,
  city: "New York"
};

const arr = Object.values(obj);
console.log(arr); // ["John", 30, "New York"]

Array to object

Similar method: Use Object.fromEntries() method, which receives an array array pair parameter and returns an object containing these key-value pairs.

Code example:

const arr = ["name", "John", "age", 30, "city", "New York"];
const obj = Object.fromEntries(arr);
console.log(obj); // { name: "John", age: 30, city: "New York" }

Difference:

• Object.values() Returns an array containing the values ​​of an object's properties, while Object.fromEntries() returns a key-value pair object containing an array of properties.
• Object.values() returns only enumerable properties, while Object.fromEntries() returns all properties whether enumerable or not.
