Getting dataTable selected records as JSON formatted data using angular

Question

Have datatable and selecting multiple records across multiple pages and trying to convert all selected records data as JSON data structure. I tried below code and getting JSON data and also two extra fields, could you please help me how to remove "check":true,"checked":true in json data.

 fnGetJsonData(){
    console.log(JSON.stringify(this.persons.filter(f => f.checked)));
 }

output:

[{"id":860,"firstName":"Superman","lastName":"Yoda","dropdown":"yuvi","check":true,"checked":true}]

expected JSON data:

[{"id":860,"firstName":"Superman","lastName":"Yoda","dropdown":"yuvi"]

You can use Array.map()

const data = this.persons.filter(f => f.checked);

const mappedData = data.map(d => ({id: d.id, firstName: d.firstName, lastName: d.lastName, dropdown: d.dropdown});

console.log(mappedData);
