How do I push an object to a JSON file with javascript?

Question

So, I have my JSON file:

{
   HomeWork: []
}

And I want to push an object: {Title: T, Due: D, Description: Desc} To the JSON file, How should I do that? I am using this right now:

async function AddWork(obj) {
workData.HomeWork.push(obj);
//RNFS.writeFile('../../json/work.js', JSON.stringify(workData));
}

I tried whit the RNFS line, but it did not help.

If you want to do that, there is no edit mode ! so be careful .

If you read it and modify it , you are doing it locally, so you need override the file you are working on.

you need to read it using Read File in fs and then after you do the modification you need to Write it on the top of the file you are working with

I hope it helps <3

as you mention rnfs i gave you the docs for that, i personally recommend using RNFetchBlob instead of RNFS! read the documentation its clear , if you got any problem write here i will help you. this link can help you https://github.com/joltup/rn-fetch-blob/wiki/File-System-Access-API#writefilepathstring-contentstring--array-encodingstring-appendbooleanpromise – Amir Doreh Jul 13 '20 at 08:23
