默认只显示问题 —— 先自己在心里答一遍，再展开对答案。答不上来就标「不会」，下次抽认卡会先抽它。Only the question shows by default. Answer it in your head first, then open the answer. Mark the ones you miss; the flashcard round puts those first.

标记不是打分，是给下一轮排队Marks are a queue, not a score
标「不会」的题会排到抽认卡最前面，标「会」的进低频池排最后。所以别客气 —— 觉得答得磕磕巴巴就标「模糊」。准备好了就去抽认卡。“No idea” jumps to the front of the next round; “got it” drops to the back. So be honest — if it came out shaky, mark it shaky. Then go run a flashcard round.

这些题从哪来Where these come from
99 道来自面试题库 #269–#387；TypeScript 深度那 6 道是 DrillLab 自出的（senior 补强，卡片上有标注）。答案都是 DrillLab 写的，所以讲解里的代码块一律标「示意」。每道题都能点回它出处的那一节课。99 questions come from the interview bank (#269–#387); the 6 TypeScript deep-dive ones are DrillLab-made (marked on the card). All answers are written by DrillLab, so every code block here is labelled “demo”. Each card links back to the lesson it came from.
