Map to names
importance: 5
You have an array of user
objects, each one has user.name
. Write the code that converts it into an array of names.
For instance:
let john = { name: "John", age: 25 };
let pete = { name: "Pete", age: 30 };
let mary = { name: "Mary", age: 28 };
let users = [ john, pete, mary ];
let names = /* ... your code */
alert( names ); // John, Pete, Mary
let john = { name: "John", age: 25 };
let pete = { name: "Pete", age: 30 };
let mary = { name: "Mary", age: 28 };
let users = [ john, pete, mary ];
let names = users.map(item => item.name);
alert( names ); // John, Pete, Mary
