How to read the hard coded json data in controller file and display its value

I am looking for a way to hardcode the json data in controller file and read the value and display it.

 var params = [
                    {
                            "id":1,
                            "title":"BA",
                            "name":"Kate"       
                    }
              ]

This is the json data I have in controller file. How can i read the data and display it in console.

if this is always going to be a single item, why are you making it an array? You could just do the following:

let params = {
  "id":1,
  "title":"BA",
  "name":"Kate"     
};

Then access the data like this:

params.id
params.title
params.name
