Question on a simple example from the backbone documentation?

Question

backbone.js

There are two methods in the primary model:

initialize: function() {
           if(!this.get("title")) {
               this.set({"title":this.defaults.title});
           }
       },
       
toggle: function() {
           this.save({done: !this.get("done")});
       },

Why in one case - title - it is necessary to take it in brackets, and in the second case - done - it is not necessary?

Answer 1

In the first case, there is also no need: it will this.set({title:this.defaults.title});work fine.
