How to filter objects with keys in arrays in JavaScript

I am new to JavaScript and I cannot solve this problem:

Instructions
Use .filter() to return only the future students that are old enough to attend DevMountain (18+ only, please).
Assign the result of filtering futureStudents to a variable called oldEnough

var futureStudents = [
  {name: "Alex", age: 30},
  {name: "Sara", age:20},
  {name: "Mark", age: 13}, 
  {name:"Charlotte", age: 3},
  {name: "Taylor", age: 18}
];
//code here
//this is what I've come up with
var oldEnough=futureStudents.filter(
  function(val){
  if(num.val>=18){
    return futureStudents.name;
  }
});

Open in new window

JavaScript

This is where your problem is:

function(val){
  if(num.val>=18){
    return futureStudents.name;
  }

Open in new window

This function should return true for any element that matches the condition, and false otherwise.
It should use the 'val' object, which represents the current value within the array.
You should not be accessing the entire 'futureStudents' array anywhere within that function.

Do these clues help point you in the right direction?
