I've been trying to learn NodeJS following this NodeJs Youtube Tutorial [LINK] . I already worked with the Fetch API [LINK] for a couple of months to get data from WordPress and Google Sheets back ends. The last videos of the Youtube playlists are about creating a To Do List app with NodeJS and the npm's express, EJS and body-parser. However, at part 4 of the To do list app [this video] , this "teacher" is using jQuery with Ajax to POST data to NodeJS ( His jQuery Code Snippet [LINK] ). Since I've only been working with fetch() for AJAX POST requests, i wanted to continue with this method in plain JavaScript.

I was doing The Net Ninja's Making a To-do App tutorial ( [this video] ). I am able to delete pre-defined items on the To-do-App but I am unable add items. Everytime I try to add an item, I get the error below. It seems there's something to do with the todos[i].item being undefined. Thanks for your time! Below is the .ejs file that contains the To-do-App. TypeError: C:\Users\dlma1\Desktop\Nodejs Practice\znode-js-playlist\views\todo.ejs:17 15| <ul> 16| <% for(let i=0;i<todos.length;i++){ %> >> 17| <li><%= todos[i].item %></li> 18| <% } %> 19| </ul> 20| </div> Cannot read property 'item' of undefined **Edit: So there were quite a few files and I didn't want to overwhelm people so I'm going to post

So... this is the exact same code from a youtube tutorial and when he typed this code and ran it, he didn't get a single error but when I did it, I got 2 errors which are ';' expected and ',' expected. The link to the original code on the tutorial: [this video] module.exports = funciton(app) { app.get('/todo', function(req, res) { res.render('todo'); }); app.post('/todo', funciton(req, res) { }); app.delete('/todo:item', function(req, res) { }); }
