.filter challenge. Need a little help!

Doing some JS practice problems and got stumped at this one. I think I’m on the right track, but I’m a little confused as to what action to put in the { } in the checkAge function.

"For this problem, we will be re-creating the functionality of the .filter function.

Begin by creating a checkAge function.
It needs to take in an array, loop through it, and return a new array containing all the numbers greater than 18."

My code:

function checkAge(val, i, arr) {
if (arr[i]>18) {
newArr = array.filter();
return newArr;


Do you have a link to the entire challenge verbiage?

If you are supposed to recreate the functionality of the filter method, then you should not be using the filter method in your checkAge function.


That was the entire explanation given.

After doing some digging online I found the same problem with the solution either

function checkAge(arr) {
return arr.filter(age => age > 18)


function checkAge(arr) { // take in an array
var greaterThan18 = []; // initialize new empty array for the greater than 18 values
for (var i = 0; i < arr.length; i++) { // loop through the given array
if (arr[i] > 18) { // if the element in the array is greater than 18…
greaterThan18.push(arr[i]) // put the element in the new array we created earlier
} // we don’t need to do anything with the other elements
that aren’t over 18, so no ‘else’ needed
} // after the for loop is finished…
return greaterThan18 // we can return the array with the elements that are greater
than 18

Arrow Functions and Array Methods are both super new to me, so this explanation was pure gold. That’s for taking a look the problem!


So do you still have questions?
