What's the deal with receiving [object Object] in my JavaScript JSON document?

Question

What's the deal with receiving [object Object] in my JavaScript JSON document?

When I use console.log(values), it returns "[object Object]" instead of logging the array as expected.

This is the code snippet I'm working with:

let values = {
    "coins": 0,
    "griffinFeathers": 0,
    "souvenir": 0,
    "cogs": 0,
    "cats": 0,
    "golems": 0,
    "champions": 0,
    "minotaurs": 0,
    "inquisitors": 0
}

JSON.stringify(FileLib.write("MinotaurLoot", "values.json", values));
function thing() {
    fileThing = JSON.stringify(FileLib.read("MinotaurLoot", "values.json"));
    if (griffin_thing_idk) fileThing.griffin++;    
}

console.log(values) // [object Object]

javascript json file

Answer №1

Examining:

JSON.stringify(FileLib.write("MinotaurLoot", "values.json", values));

JSON.stringify() must be eliminated because the resulting stringified version of your Object is not being stored anywhere or you could try this approach:

const stringifiedValues = 
    JSON.stringify(FileLib.write("MinotaurLoot", "values.json", values));

//Now you should be able to avoid [object Object] in console.log
console.log(stringifiedValues);

The reason why you see [object Object] is because JavaScript's default implementation of console.log() does not handle Complex Objects as nicely as primitive data types like String or Number.

@coderpc mentioned in their comment on your post that using JSON.stringify() before logging an object can help reveal its contents inside a console.log statement.

Give it a try and let us know if it resolves the issue.
