Hi Matthew thanks for your contribution! For your second example, you have 2 typos, brackets instead of parenthesis next to function, and Objects instead of Object. Here it is corrected:

function removeDuplicates(array) {
let x = {};
array.forEach(function(i) {
if (!x[i]) {
x[i] = true;
return Object.keys(x);
