There seems to be a culture of collecting Udemy courses among fledgeling web developers.
Young web developers certainly seem to love video courses for some reason. Maybe I'm just old and crotchety, (well, one of those is certainly true), but I would much rather get my fix textually and go along at my own pace. Flipping pages or scrolling is still superior to trying to scrub through a video timeline.
Well, that's a different use case.
Videos are good for exact instructionals, because of this, they are quite good for getting to the bare metal quickly and getting a quick - albeit incomplete - understanding of the technology.
Following a tutorial online on a webpage is a bit different as it's not a follow along, (you don't get told exactly what to click and "see" someone doing it) so it requires a bit more parsing and effort on your part. (Which can often be better for learning, but not always).
Generally my workflow for learning a new tech is starting with a good instructional video (like udemy) for the basic grounding, then move onto the technical documentation to develop an actual well grounded understanding.
Videos have their downsides, (you can get through an entire video series and not actually know how to self-guide) but they are much better in my opinion at lowering the barrier of entry.
Text is much better for someone wanting to learn specific things, or connecting concepts together, and/or reference documentation, searching for concepts.. etc.
The other point that I'm unsure if it is just me or all people, but I've started loving udemy videos because I can follow along with it a lot easier when I have tired eyes and worn out brain after a full day of work. I often struggle to teach myself a new technology when I'm completely worn out from my job.
