Convert javascript array into json array

Question

I have a javascript array

var arr = ["value1", "value2", "value3", "value4", "value5"]

I want to convert it into JSON array to be sent over to server like this

{
  "JSONarray": ["value1", "value2", "value3", "value4", "value5"]
}

Directly putting javascript array varible into the value doesn't help.

Tried JSON.stringify() it converts the whole array into one giant string.

Is there any other approach to this problem?

{ "JSONarray": ["value1", "value2", "value3", "value4", "value5"] } u want to make this ? — Ayeshmantha Perera, Aug 04 '18 at 03:25

To clarify, JSON is a string and not an object hence it's abbreviation of JavaScript Object Notation. The constructed output in the example is colloquially referred to as a POJO or Plain Old JavaScript Object. They are different. :)

JSON exists as a string — useful when you want to transmit data across a network. It needs to be converted to a native JavaScript object when you want to access the data. This is not a big issue — JavaScript provides a global JSON object that has methods available for converting between the two. - MDN

The approach for sending JSON in JavaScript is to use the builtin JSON object's stringify method as you have already discovered.

You want to use JSON.stringify() to convert the data into a string. This makes it simple when transferring data.

When you or someone receives this string of data, you can convert it to 'json' with JSON.parse()

var JSONarray = JSON.stringify(arr)
// => "["value1","value2","value3","value4","value5"]"
JSON.parse(JSONarray)
// => (5) ["value1", "value2", "value3", "value4", "value5"]
