I've used Safari Books, Pluralsight and Egghead.io. Pluralsight was pretty good. I got a lot out of a number of videos. Since they cover a variety of topics, it was great to spin up on something when I needed it. For instance, I was working with Redis and needed to pick up Lua so I took an hour, watched a video and was on my way. This was about a year ago and their selection around Javascript was a little lacking for the topics I wanted but that has probably changed by now. Safari Books is fantastic if you like to read. They also have a ton of books on other topics so it makes it a much wider resource depending on your goal. At the time, I was doing quite a bit of "intrapreneurship" so it was nice to grab a book on product development, business and entrepreneurship. I currently have a subscription to Egghead.io which is way more front-end focused. Around Christmas, they tend to offer a year long subscription for a reduced price which I picked up. The topics don't tend to be as varied as Pluralsight but I think the depth of a lot of them is really good. For instance, I got more out of the Egghead videos around Angular and React than I did from Pluralsight.
