This is honestly the best class tutorial I've seen. I just needed to know the syntax but literally, every time I googled it, I would just be confused by people who weren't answering my question. Thank you so much for this video.

Thank you for such a nice video. class User{ constructor(firstname, lastname, credit, middlename){ this.firstname = firstname; this.lastname = lastname; this.credit = credit; this.middlename = middlename; } addMiddleName(middlename){ const fullname = middlename.split(' '); console.log('New name for adding middlename',fullname); this.middlename = fullname[1]; console.log(`Updated name: ${this.firstname} ${this.middlename} ${this.lastname}`); } }

Hello sir, my name is Nilesh and I am following your javascript course. It is really helping me to get started with javascript from basics. I followed every video of Javascript. so my question is can I start learning react.js where I already bought your udemy course of React in last month but haven't started it... or do I need to do any advance javascript course or any node.js which are available on udemy(or any other online website including yours) I hope I get reply as soon as possible because I am so excited to learn react and want complete some future projects. 😀
