问题 When running JS scripts in Chromes' Performance tab, I see there are three steps for JS interpretation: Parse , Compile and Evaluate . Sometimes I just see Evaluate , sometimes Compile and Evaluate and sometimes it's the whole three. My questions are: What each step actually means? Why sometimes there are missing steps? (for instance, sometimes Parse is missing) 回答1: Parse: The js engine goes over the code, determines all the different scopes, variable declarations etc. and sorts them. At

问题 For my app, I need to radically change the entire UX for touch devices using an onscreen keyboard (eg. mobile, touch TV) vs mouse/kbd devices (eg. desktop, a mobile with a bluetooth mouse/kbd). NB. I've already grokked responsive layout with CSS grid and media queries, so that aspect is dealt with. My issue isn't one of layout, it's that the entire UX needs to be fundamentally different.
