Stop JSON.parse from shuffling the order of an object

Stop JSON.parse from shuffling the order of an object

When working on my web application, I retrieve a JSON string from the server and store it in a variable called greetings:

var greetings = '{"2":"hoi","3":"hi","1":"salam"}'

I have observed that the greetings begin with index 2 and value hoi. After attempting to parse the JSON, I noticed the following result:

JSON.parse(greetings) // {1: "salam", 2: "hoi", 3: "hi"}

The order of the elements has changed. It appears that JSON.parse organizes the output based on the keys.

Is there a method to maintain the original ordering of the string?

Answer 1

Answer №1

{
   "2":"hello",
   "3":"hey",
   "1":"hi there"
}

This is not an array; it's actually an object. Objects do not follow any specific order. If maintaining a particular sequence is important, consider using a real array instead.

Answer 2

{
   "2":"hello",
   "3":"hey",
   "1":"hi there"
}

This is not an array; it's actually an object. Objects do not follow any specific order. If maintaining a particular sequence is important, consider using a real array instead.

When dealing with objects, it is important to note that the order of indices cannot be relied upon. It is recommended to use an array of key/value pairs instead.

The keys in objects are usually parsed as numeric indices, resulting in an ordered sequence. One workaround for this behavior is to prefix your keys and then remove those prefixes later:

console.log(JSON.parse('{"i2":"hoi","i3":"hi","i1":"salam"}'))
