I have a object array in javascript. Example:

objArr = [{"FirstName":"John","LastName":"Doe","Age":35},{"FirstName":"Jane","LastName":"Doe","Age":32}]

I want to create an object array like this

newObjArr=[{"Name":"John Doe","Age":35},{"Name":"Jane Doe","Age":32}]

How should I do this?

You can use Array.map

The map() method creates a new array with the results of calling a provided function on every element in the calling array.

const objArr = [{"FirstName":"John","LastName":"Doe","Age":35},{"FirstName":"Jane","LastName":"Doe","Age":32}]


const newObjArr = objArr.map(({FirstName, LastName, Age}) => {
    return { 
      Name: `${FirstName} ${LastName}`,
      Age
    };
});

console.log(newObjArr);

Or an ugly one liner:

objArr.map(({FirstName, LastName, Age}) => ({ Name: `${FirstName} ${LastName}`, Age }));
