Destructuring assignment

importance: 5

We have an object:

let user = {
 name: "John",
 years: 30
};

Write the destructuring assignment that reads:

  • name property into the variable name.
  • years property into the variable age.
  • isAdmin property into the variable isAdmin (false, if no such property)

Here’s an example of the values after your assignment:

let user = { name: "John", years: 30 };
// your code to the left side:
// ... = user
alert( name ); // John
alert( age ); // 30
alert( isAdmin ); // false
let user = {
 name: "John",
 years: 30
};
let {name, years: age, isAdmin = false} = user;
alert( name ); // John
alert( age ); // 30
alert( isAdmin ); // false
