This was a nice, compact course that did a good job of introducing the user to the intricacies of the document object model, or DOM. I thoroughly enjoyed it.

Great content with best explanation that cleared all my concepts and thanks for that course.

Good course. One tip is to go a little bit slower on explaining what you're doing. I couldn't keep up with the pace and had to pause and rewind the videos several times.

Me parece un curso muy claro y conciso. Principalmente por qué no hablo ingles pero entendí la mayoría de los conceptos que se trabajaron

Skips over some scene such as at 6 and goes so fast
By Leland B Nicholson on 7/11/2019
I am looking for a simple course that shows standard JavaScript/ES6 (no libraries), the DOM, and an object oriented approach. I am teaching AP Computer Science Principles, and all of the course material I have uses their own libraries without explaining how a student would get from standard JS to the simplified "JS" they are teaching with. This comes very close. Thank you!

He is clear, uses good programming conventions and is a lot of fun. Leaves you with a good project to continue to grow, well done!

it was actually as brief and nice as expect although short but the basics where covered, well enjoyed.
By Jeremy Rackley on 4/10/2019
This course was offered for free, and I decided to give it a try before I purchased the Monster Javascript course. This is a great learning tutorial. You are the first teacher that has actually explained how to tie together html, css and javascript. I love this. Thank you.
