const dummy = {
  id : '1',
  description : 'Wow awesome'
};

console.log(dummy.description);

//-------------------------------------

const descData = dummy.description;

console.log(descData);

variableName['description'] or variableName.description

First You need to parse it using JSON.parse. Then using . or [] you can access. For Ex:-

var a = '{
    "id": "149",
    "description": "Try"
}'

b = JSON.parse(a)

b['description'] or b.description FOr more reference you can study here
