o.name = name;

return o;

var person1 = createPerson ("Nicholas");
alert(person1.name);

    return is a JavaScript keyword that causes the function it’s placed in to exit with the specified value (called the “return value”).

    In this case, it causes the createPerson() function to come to an end, returning the o object to the caller of the function.

    The o object, once returned from createPerson(), then gets assigned to the person1 variable.

    So the net result is that control flow starts here

    var person1 = createPerson ("Nicholas");

    then jumps into the createPerson() function, which creates a new object representing a person with the name “Nicholas”, then returns it, which brings the execution back to that line, with person1 getting the newly created person that the function returned.
