Sort array by firstname (alphabetically) in Javascript

Question

I got an array (see below for one object in the array) that I need to sort by firstname using JavaScript. How can I do it?

var user = {
   bio: null,
   emai

Just for the record, if you want to have a named sort-function, the syntax is as follows:

let sortFunction = (a, b) => {
 if(a.firstname < b.firstname) { return -1; }
 if(a.firstname > b.firstname) { return 1; }
 return 0;
})
users.sort(sortFunction)

Note that the following does NOT work:

users.sort(sortFunction(a,b))
