If you just want to get rid of the reference to this, you could do:
app = {
foo: 'afoo',
bar: 'abar',
callbackLib: {
replyFoo: function () {
console.log(app.foo);
},
replyBar: function () {
console.log(app.bar);
}
},
doSomeThing: function (){
app.callbackLib.replyFoo();
app.callbackLib.replyBar();
}
}
app.doSomeThing();
Although this would trigger errors in the following case:
bar = app;
app = {};
bar.doSomeThing();
As app is now no more.
