values getting repeated in object after regex pattern in JavaScript

Question

Could someone tell me why particular key value getting repeat in object?

I've data like below getting from response like below.

var data = {
      "sub": {
        "LoadTime on linkedShip": "01:25:00 AM",
        "business Limit": "300",
        "avoid goods": "50",
        "avoid goods_Group": "100",
        "isPermanent": "['permLinkAccount']",
        "transport Limit": "1",
        "hasDailySlot": "1"
      }
    };

trying to replace "isPermanent": "['permLinkAccount']" to "isPermanent":"permLinkAccount" without changing other stuffs in object.

if (data.sub.hasOwnProperty("isPermanent")) {
  
  data = JSON.parse(JSON.stringify(data).replace(/[\[\]']/g,"permLinkAccount"));
  console.log('data', data);
}

but getting like isPermanent: "permLinkAccountpermLinkAccountpermLinkAccountpermLinkAccountpermLinkAccount" instead of "isPermanent":"permLinkAccount"

I need like

    LoadTime on linkedShip: "01:25:00 AM"
    avoid goods: "50"
    avoid goods_Group: "100"
    business Limit: "300"
    hasDailySlot: "1"
    isPermanent: "permLinkAccount"
    transport Limit: "1"

fiddle is here

What is wrong here?

Per your regex you are replacing [, ', and ] with permalinkAccount (hence the result) where you want to actually filter them out of the expression.

Just use and empty string as a replacement instead.

console.log("['permLinkAccount']".replace(/[\[\]']/g, ""))

Or

console.log("['permLinkAccount']".replace(/\W/g, ""))

Try just parsing the JSON into an object and work with the object, it's easier.

const dataObj = JSON.parse(data);
if (dataObj.hasOwnProperty("isPermanent")) {
  dataObj.isPermanent = "permLinkAccount"
}

I think the idea is the OP doesn't know what the value of "permLinkAccount" is ahead of time...
