Can't access object property, even though it shows up in a console log

Question

Below, you can see the output from these two logs. The first clearly shows the full object with the property I\'m trying to access, but on the very next line of code, I can\

Answer 1

I had an issue like this, and found the solution was to do with Underscore.js. My initial logging made no sense:

console.log(JSON.stringify(obj, null, 2));

> {
>   "code": "foo"

console.log(obj.code);

> undefined

I found the solution by also looking at the keys of the object:

console.log(JSON.stringify(Object.keys(obj)));

> ["_wrapped","_chain"]

This lead me to realise that obj was actually an Underscore.js wrapper around an object, and the initial debugging was lying to me.
