What this "get" in JavaScript object means?

Question

Look at this script:

var human = 
{
   firstName: 'Saeed',
   lastName: 'Neamati',
   get fullName() {
       return this.firstName + ' ' + this.lastName;
   }
}

I don't know what get means in this context.

Answer 1

It identifies an object property that's returned when the property is read.
