Object.keys, values, entries In Javascripts

For plain objects, the following methods are available in Javascript

• Object.keys(obj) – returns an array of keys.
• Object.values(obj) – returns an array of values.
• Object.entries(obj) – returns an array of [key, value] pairs.

For instance:

let user = {
  name: "Technical Architect",
  age: 30
};

• Object.keys(user) = ["name", "age"]
• Object.values(user) = ["Technical Architect", 30]
• Object.entries(user) = [ ["name","Technical Architect"], ["age",30] ]
