unexpected token ')' error 

const toggleList = document.getElementById('toggleList');
const listDiv = document.querySelector('.list');
const input = document.querySelector('input');
const p = document.querySelector('p.description');
const button = document.querySelector('button');

toggleList.addEventListener('click', () => {
    if () {
      listDiv.style.display = 'block';
} else {
      listDiv.style.display = 'none';
}
})

button.addEventListener('click', () => {
    p.innerHTML = input.value + ":";
});

It's happening in the if statement, I seriously have looked over this code 100 times now.

Your if statement is empty but it needs a conditional. You should give it a condition for when it should display the element.

I have it typed out exactly the way it is written by the instructor. What condition would I put in there? All the examples and problems we have been working out have all included empty ()

Alex. At around 5:30 in the associated video, Guil explains how you should populate that 'if statement'.

Viewing your current code in my code editor (VSC), it literally identifies the closing bracket of your empty if statement as being problematic, which is your unexpected token ')' error.

Yeah I totally noticed that when I opened my laptop up again the next day. Thanks for hanging in there through my mental fart
