What is the best way to transform a JavaScript array into a neatly formatted JSON string?

Imagine having an object structured as follows:

var test = {
    jsonString: {
        groups: ['1','2','3','4','5']
    }

}

How could you transform it into a JSON string like this?

var test = {
    jsonString: "{\"groups\":[\"1\",\"2\",\"3\",\"4\",\"5\"]}"
  }

I find myself a bit confused on how to achieve this. I'm not entirely convinced that JSON.stringify(test.jsonString) would provide the exact output I desire. Any guidance or assistance in the right direction would be greatly appreciated! Thank you!

Answer №1

Absolutely, performing those steps is crucial. Afterwards, reassign it to the respective property.

let example = {
    jsonData: {
        categories: ['apple', 'banana', 'orange', 'pear']
    }
}

example.jsonData = JSON.stringify(example.jsonData);
console.log(example);

Answer №3

If you want to convert an object into a JSON string, you can utilize the JSON.stringify method

var example = {
   data: {
       items: ['apple','banana','cherry','date','grape']
   }
}

var jsonOutput = JSON.stringify(example.data);

Here is the output after using JSON.stringify:

"{"items":["apple","banana","cherry","date","grape"]}"
