What is the process to combine multiple fields from objects within an array and create a new array of objects?

edit

The process to combine multiple fields from objects within an array and create a new array of objects typically involve the following steps:

1. Define the fields that need to be combined from the original objects.
2. Loop through the original array of objects and for each object, create a new object that combines the desired fields.
3. Push the new object into a new array.
4. Return the new array.

For example, suppose we have an array of objects that represent people with fields for "firstName", "lastName", "age", and "gender". We want to create a new array of objects that combine the firstName and lastName fields into a single "name" field. Here's a function that would achieve this:

function combineFields(originalArray) {
  let newArray = [];
  for (let i = 0; i < originalArray.length; i++) {
    let newObj = {
      name: originalArray[i].firstName + " " + originalArray[i].lastName,
      age: originalArray[i].age,
      gender: originalArray[i].gender
    };
    newArray.push(newObj);
  }
  return newArray;
}

This function loops through the original array of objects, creates a new object for each one with a combined "name" field, and pushes it into the new array. It then returns the new array.
