Am I the only one who finds these new JS lessons hard to understand?

Just asking, am I the only one who finds the new lessons hard to understand

I mean before, lessons were easy-mid, but now the new ones just don’t seem to have the same quality like the old ones.

Just asking to know if I’m the only one and needs more practice or it’s for everyone.

I actually think the lessons are either hit or miss.

Sometimes i feel i learnt something or its too straightforward. But i do not think its different from before.
