I need convert following in the EXACT format shown below with javascript, could you please suggest how to achieve this
from: {"healthy":true,"unhealthy_reasons":[]}
to: [{"healthy":true,"unhealthy_reasons":[]}]
If that's all you need to do, you can just wrap array brackets around the variable that contains the object:
let initialObject = {"healthy":true,"unhealthy_reasons":[]};
let arrayedObject = [initialObject];
But I'm wondering if there's more to this. If this is actually part of a more complicated task, just add that to your question and you'll get a more complete answer.
Use JSON.parse() and JSON.stringify()
let data = '{"healthy":true,"unhealthy_reasons":[]}';
let parsed = JSON.parse(data);
//TO get an array
console.log([parsed])
//TO get a string
console.log(JSON.stringify([parsed]))
