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
|
1 2 3 4 5 |
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,
|
1 2 3 4 |
var {name, age} = {name: 'John', age: 32}; console.log(name); // John console.log(age); // 32 |
