Javascript Array Key & Value Selecting

So, I'm saving a obj like

var user = {"username": username, "info": info};

The thing is, this will be saved in an array, if I want to access ONLY that user how would I go about doing that? I'm usering array.push to add it to an array.

You can either use Array.find or Array.filter.

var users = [
  {"username": "Bob", "info": "..."},
  {"username": "Alice", "info": "..."}
];

function getUserByName( name ) {
  var result = users.filter(function (u) {
    return u.username === name;
  });
  return result.length ? result[0] : null;
} 

console.log(getUserByName("Bob"));
console.log(getUserByName("Unkown"));

Note: The above snippet does not take duplicates usernames in account. It will return the first one it finds.
