Question

I am reading the annotated source code of backbone.js and it mentions “attribute hash”. What is that?

Set a hash of model attributes on the object, firing “change” unless you choose to silence it.

My understanding is it is an object, array, etc, or does hash refers to any format in particular?

Answer 1

It’s an object, really:

var attributes = {
    option1: 'on',
    option2: 'off',
    option3: true,
    option4: 145
};

alert(attributes.option1); // on
