Really good work, Fevi!

I think here you just had a wrong thinking, if you look at the solution in the Student Portal, then you will understand it quickly!

here you miss the if condition:

if (wordsUnique.length == 0){
        return null
    }

// Loop through array values
for (i = 0; i < wordsUnique.length; i++) {
if (uniqueArray.indexOf(wordsUnique[i]) === -1) {
uniqueArray.push(wordsUnique[i]);
}
}
return uniqueArray;

For the last tasks I would say: look at the solution in your own time and if you have any questions, ask Karina, Marian or me (Joanne).

// Iteration #6: Find elements
const wordsFind = ['machine', 'subset', 'trouble', 'starting', 'matter', 'eating', 'truth', 'disobedience'];

But one more thing: you never know which words you really have in the array. So you can't compare with specific words. It should work for any array of words.
