My first impression is that your presentations are not as well organised as the the OP ones. For example, looking at the Javascript Classes and Inheritance Tutorial, you end up correcting your typing out of "Prototype inheritance vs Classical inheritance" at least 6 times. This is very distracting and detracts from the the quality of your presentation. Why don't you have these sorts of things pre-prepared?

Additionally, the OP's entire Youtube channel is very cleanly laid out and easy to navigate. Yours is somewhat of a mess and cluttered.

I will still have a more detailed look at your presentations and appreciate the link, but feel you could do a lot better.

BTW. The OP's videos also have issues, mainly with the consistency of volume levels across different videos but his channel is generally an excellent example of this sort of online education.
