Robust, mature, good knowledge of JavaScript.
Also you can learn(for extending knowledge) cli(npm, git, etc), design patterns, testing, reactive programming(good to know too).
But the most important is JavaScript

you should have basic knowledge of html and css, javascript, typescript, understand http related topics for a start. you don't have to be proficient in them as you can research something you don't understand while you study about angular
