Transform a string containing square brackets and double quotes into an array

How can I transform the following string into an array with individual values?

["X", "Y", "Z"]

The output should be like:

arr[0] // X
arr[1] // Y
arr[2] // Z

Answer №1

Your input is not in the form of a string, but rather an array. In order to parse it using JSON.parse, your string should follow the correct JSON format as shown below:

'{"yourArray":["A","B"]}'

To convert this array correctly in JavaScript, you can simply copy it into a variable and use code similar to the following:

let arr = ["A", "B"];
console.log(arr[0],arr[1]) //  A, B .

Answer №2

let data = JSON.parse(myData);

console.log(data[0]) // First item
console.log(data[1]) // Second item

Answer №3

If you have received this data in the form of a string, you can easily convert it into an array using the JSON.parse() method.

var parsedArray = JSON.parse(receivedData);
console.log(parsedArray);

This will transform your stringified data into a usable array. If you're wondering why you can't simply work with the original array you received, try using

console.log(receivedData.split(''));

You'll see that what you actually have is just one long string. I hope this explanation clarifies things for you.
