What does it mean to add to the options hash in Backbone?

Question

JavaScript

I can't figure out where?
It is written that for validation to the model.set method, you need to add {validation: true}

I add

name.set("age", 20, {validation:true})

But it does not work

Answer 1

Method signature
I suspect that you need to write either this way
or pass it to the constructor
new Model([attributes], {validation:true})
