Sort an array of objects

Question

Can someone help me sort an array of object using map method, and/or any other optimal means, based on the code below.

I used sort for it, but I'm thinking it may not be the most efficient way of doing it.

I sorted by using the objects age key. How do I sort by a key whose value is a string?

Answer 1

I did something by sorting them by alphabetical order..but I didn't understand whether I have to sort it by it's name or age..

person.sort(function(a,b){
return a.name.localeCompare(b.name);
})

Answer 2
