Uncomfortable lecture First of all, using paid WebStorm is also like that.. Every time I type, the screen shakes, and every time I paste, it feels like a bomb is going off. You speak very slowly, but the screen changes are at the speed of light, so sometimes I have to turn it over several times because of the screen changes. My computer is Windows, but it would have been nice if you had told me how to build both Mac and Windows. Even if you couldn't tell me everything on the Windows side, it would have been nice if you had mentioned some key points. The content seems good... I'll look forward to the next lecture.
