I have just finished watching WebStorm Fundamentals, a Pluralsight course on the JetBrains IDE.
I have never actually used it – although I have used other IDEs by JetBrains – so there was a lot of interesting things compared to my usual JS/HTML IDE (Notepad++, for minimal touch-ups on my main site).
The course only takes a few hours, and was pretty clear. I viewed most of it at 120% speed, and the instructor was still very clear at this speed.
Overall, recommended if you already have access to PluralSight courses and are interested in WebStorm.
