Bug 158262 – JSON.stringify replacer function calls with numeric array indices

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Brian C]

Since

> typeof Object.keys(['a'])[0] === 'string';

I would expect

> JSON.stringify(['a'], function(key, value) {
>   console.log(typeof key);
>   return value;
> });

to log "string" twice. Instead it logs "string" and then "number".

Chrome and Firefox log "string" twice, as expected.

I'll have a look.

Looks like a test needs an update. I'll do that tomorrow.
