The result is returning {firstname: ‘Mike,Henry,Pete’, lastname: ‘Port,Split,Micky’}
I want result to return
{
firstName: Mike,
lastName: Port
},
{
firstName: Henry,
lastName: Split
},
{
firstName: Pete,
lastName: Micky
}

var data = "Mike Port, Henry Split, Pete Micky";
var firstName = [];
var lastName = [];
var result = [];
var newNames = data.replaceAll(", ", ",");
var fullName = newNames.split(',');
fullName.forEach(name => {
  let splitted = name.split(" ");
  firstName.push(splitted[0]);
  lastName.push(splitted[1]);
});

f_name_list = firstName.toString().split(", ");
l_name_list = lastName.toString().split(", ");

for (let i = 0; i < f_name_list.length; i++) {
  result.push({ 
    firstname: f_name_list[i],
    lastname: l_name_list[i]
  });
}

console.log(result);

>Solution :

split data with ", " then split with " "

var data = "Mike Port, Henry Split, Pete Micky";
var result = [];
var newNames = data.split(", ");
newNames.forEach(name => {
  let splitted = name.split(" ");
  result.push({ 
    firstname:splitted[0],
    lastname: splitted[1]
  });
});

console.log(result);
