JSON.parse incorrectly transforming string to char

I have a string like this:

 const str =  { "_id": "x", "test": "rxh", "access_data": { "account" : "1", "password" : "r\u0026", "name" : "eu" } }

And i am using JSON.Parse to parse this string. The problem is that the parse understant the part "\u0026" of my password as a unicode, and transforms it to "&"

if I try JSON.Parse(str) the return is:

{
  _id: 'x',
  institution_id: 'rxh',
  access_data: { account: '1', password: 'r&', name: 'eu' }
}

How can I avoid this transformation?

To encode a literal back slash, use two backslashes (\\)

JSON.parse(String.raw`"r\\u0026"`) === String.raw`r\u0026`

If you're using JSON.stringify where you produce the JSON string, it should take care of this for you:

let dataBundle = { password: String.raw`r\u0026` };
console.log(JSON.stringify(dataBundle));

Also, please be very careful about passing passwords in plain text. I don't know your situation, but it's best to leave account sign-in to widgets that do that for you. They often salt passwords before sending them over the network.
