[ES6] 12. Shorthand Properties in ES6

Where destructuring in ES6 allows you to easily get properties out of an object, this shorthand property syntax allows you to easily push properties in.

let firstName = "Answer";
let lastName = "Question";

let person = {firstName, lastName}

console.log(person);  // { firstName: ‘Answer‘, lastName: ‘Question‘ }

let mascot = "Moose";

let team = {person, mascot};

console.log(team); // { person: { firstName: ‘Answer‘, lastName: ‘Question‘ },
                   //mascot: ‘Moose‘ }
