Usage
------------------------------------------------------------------------------

The best usage guide is the RFC itself emberjs/rfcs#494
but here are a few examples of "before"/"after" to whet your appetite:

Before:

`js
const Person = EmberObject.extend({
firstName: null,
lastName: null,

fullName: computed('firstName', 'lastName', function() {
return ${this.firstName} ${this.lastName};
}),


fullNameChanged: observer('fullName', function() {
// do something :)
}),
});
`

After:

`js
const Person = EmberObject.extend({
firstName: null,
lastName: null,

fullName: computed('firstName', 'lastName', function() {
return ${this.firstName} ${this.lastName};
}),


fullNameChanged: observer({
sync: false,
dependentKeys: ['fullName'],
fn() {
// do something :)
}
}),
});
``
