Javascript - Remove Special characters and associated strings in Json object

i'm trying to fix and get expected result but am failed. 

let sample obj= 
[{ profile: admin, availableAction: 'You have [Access: write][Option: print] only few options'},
{ profile: cust, availableAction: 'You have [Access: write][Option: print] only few options'}
]

i want to print only 'You have only few options'

to achive this, i tried below possible way but failed

  for (let key in obj) {
      if (obj.hasOwnProperty(key)) {
          console.log('KEY---->', key + ' -> ' + obj[key]);

          if (obj.includes('[Access: write][Option: print] ')) {
            obj = obj.replace(/\[(.*)\]/, '');
          }
      }
  }

but getting cannot read property error.

could some one tell me how to fix this properly.

Note: I know its duplicate thread, i tried as much as possible solution from SO. but couldn't make use of it effectively.

Thanks in advance

You can take advantage of a replacer function that can be passed to JSON.stringify. After stringification you can parse the JSON string back to an object using JSON.parse

let obj = [
  { profile: "admin", availableAction: 'You have [Access: write][Option: print] only few options'},
  { profile: "cust", availableAction: 'You have [Access: write][Option: print] only few options'}
];



const result = JSON.parse(JSON.stringify(obj, (k, v) =>
  (k === "availableAction") 
    ? v.replace('[Access: write][Option: print] ', '') 
    : v
));

console.log(result)
