Many Linux and Unix developers are familiar with the GNU debugger (GBD), the invaluable open source tool for testing, fixing, and retesting software. And since GDB can be ported to Windows, Microsoft

這不是一本給初學者的JavaScript教科書。相反地，它是寫給那些已經學過JavaScript卻依然感到卡關，對某些觀念依然模糊的開發者。就像大學課程一樣，或許都是死背答案，考試時題目一變就被當掉了。這時該怎麼辦呢？重修就好。那為什麼要再學一次呢？因為我相信許多人第一次都沒有真的把這些觀念學進去，只是為了應付面試而已，面試結束就忘了。這也合理，因為許多地方都是教你這些知識，卻沒告訴你要用在哪裡。這本書共分成了五個章節，分別是：1. 從重新認識JavaScript開始2. 重要與不重要的資料型別3. 物件與有趣的prototype4. 從scope、closure以及this談底層運作5. 理解非同步每個章節都對應到了一些令初學者很頭痛的話題，而你至少可以找到底下疑問的解答：1. 知道this是什麼要幹嘛？2. 知道[]+{}的結果是重要的嗎？3. Closure到底可以用在哪裡？4. Prototype chain好複雜，為什麼又是prototype又是__proto__？5. 理解Event loop中的microtask可以幹嘛？6. Call by value、call by reference還是call by sharing，重要嗎？7. 我怎麼知道自己學習的東西是不是對的？8. 我學這些知識在實際開發中到底有什麼用？本書不教你死背知識，而是給你一個合理的學習理由，並且藉由實際的案例來帶入這些知識，告訴你為什麼要學習，在開發時又會用在哪裡。有些人會說「以後AI要取代軟體工程師了，還需要學這些嗎？」，如果你現在就打算轉行，那確實不需要了。但我相信AI無法完全取代，還是要有人負責debug跟確認AI寫的東西，並負起責任。當僧多粥少時，誰的硬實力比較強，就有越多的優勢，而這就是在AI時代下繼續學習的理由。在《JavaScript重修就好》這本書中，會秉持著重修的精神，相同的語法、相同的知識，但是為讀者帶來嶄新的體驗，並且發現這些知識背後的關聯以及學習的美好之處。我們會逐個擊破那些JavaScript中的重要概念，更進一步去理解它的原理以及特別之處，還有在實際開發上的應用。
