I copied everything from the video and stared at the code for 20 minutes trying to find some syntax error, even went into the console to see if I could find any errors but there is none there.
const toggleList = document.getElementById('toggleList');
const listDiv = document.querySelector('.list');
const descriptionInput = document.querySelector('input.description');
const descriptionP = document.querySelector('p.description');
const descriptionButton = document.querySelector('button.description');
const addItemInput = document.querySelector('input.addItemInput');
const addItemButton = document.querySelector('button.addItemButton');
const removeItemButton = document.querySelector('button.removeItemButton');
const listItems = document.getElementsByTagName('li');
listDiv.addEventListener('mouseover', (event) => {
if (event.target.tagName == 'LI') {
event.target.textConent = event.target.textContent.toUpperCase();
}
});
listDiv.addEventListener('mouseout', (event) => {
if (event.target.tagName == 'LI') {
event.target.textConent = event.target.textContent.toLowerCase();
}
});
toggleList.addEventListener('click', () => {
if (listDiv.style.display == 'none') {
toggleList.textContent = 'Hide list';
listDiv.style.display = 'block';
} else {
toggleList.textContent = 'Show list';
listDiv.style.display = 'none';
}
});
descriptionButton.addEventListener('click', () => {
descriptionP.innerHTML = descriptionInput.value + ':';
descriptionInput.value = '';
});
addItemButton.addEventListener('click', () => {
let ul = document.getElementsByTagName('ul')[0];
let li = document.createElement('li');
li.textContent = addItemInput.value;
ul.appendChild(li);
addItemInput.value = '';
});
removeItemButton.addEventListener('click', () => {
let ul = document.getElementsByTagName('ul')[0];
let li = document.querySelector('li:last-child');
ul.removeChild(li);
});

event.target.textConent = event.target.textContent.toUpperCase();
and here:
event.target.textConent = event.target.textContent.toLowerCase();
It should be textContent
instead of textConent

Front End Web Development Techdegree Graduate 15,544 PointsNo idea why it's not working for me. None of the list items get capitalized.

Front End Web Development Techdegree Graduate 15,544 PointsI just tested this code from Guild on the next version of the editor on the next video where this is the starting piece of code. Even there it doesn't work. I'm using google chrome. fully updated. So what's going on here? Why is that specific piece not working? I'm worried right now that some of these things I'm learning here won't work.
