Object with "number" keys are stringyfied as arrays

[richarddd]

If i run this code i would expect the resulting object to be {params: {"2": "1"}}

qs.parse(qs.stringify({params: {"2": 1}}))

Qs parses it as:
{params: ["1"]}

Since qs.stringify({params: {"2": 1}}, { encodeValuesOnly: true }) produces 'params[2]=1', this seems like an issue with parse.

However, while qs.parse('params[2]=1') produces { params: [ '1' ] }, qs.parse('params[2]=1', { allowSparse: true }) produces { params: [ <2 empty items>, '1' ] }, so i think the thing you're looking for is the allowSparse option?

Hi, we are having the same issue, however we only observe it on numbers up to 20.

So for example, this will work correctly:

{params: {"21": "1"}}

but not this:

{params: {"20": "1"}}

I don't have the allowSparse option (FYI we are using qs version 6.7.0)

Any ideas? Thanks.

@dessskris thats because the arrayLimit option defaults to 20.
