Flatten

flatten is a option in select query which will flatten array data into primitive data.

e.g - Consider your data stored is :-

{
    name:"ujjwal gupta",
    hobbies:["travelling", "motorcycling"]
}

In the above example - hobbies column is array.

After flattening data will become

[
    {
        name:"ujjwal gupta",
        hobbies:"travelling"
    },
    {
        name:"ujjwal gupta",
        hobbies: "motorcycling"
    }
]

Query

select({
    from:"Members",
    flatten:true
})

flatten is useful when you are doing join. Check this issue - https://github.com/ujjwalguptaofficial/JsStore/issues/188
