Which is "better" to use for creating getters and setters?

[h1lo]

Using the Object.defineProperty() method, or manually writing getters and setters in your object?

Reasons one might be better than the other:

1. Readability?
2. Shorter code to type?

Object.defineProperty() Example:

const person = {
    firstName: 'Jimmy',
    lastName: 'Smith'
};
Object.defineProperty(person, 'fullName', {
get: function() {
return firstName + ' ' + lastName;
},
set: function(name) {
let words = name.split(' ');
this.firstName = words[0] || '';
this.lastName = words[1] || '';
}
});
console.log(person.fullName)

Manual Example:

const person = {
    firstName: 'Jimmy',
    lastName: 'Smith',
    get fullName() {
        return this.firstName + ' ' + this.lastName;
    },
    set fullName (name) {
        let words = name.toString().split(' ');
        this.firstName = words[0] || '';
        this.lastName = words[1] || '';
    }
}
