What is destructuring assignment

The destructuring assignment is a JavaScript expression that makes it possible to unpack values from arrays or properties from objects into distinct variables. Let's get the month values from an array using destructuring assignment

  var [one, two, three] = ["JAN", "FEB", "MARCH"];

  console.log(one); // "JAN"
  console.log(two); // "FEB"
  console.log(three); // "MARCH"

and you can get user properties of an object using destructuring assignment,

  var { name, age } = { name: "John", age: 32 };

  console.log(name); // John
  console.log(age); // 32
