JavaScript Pocket Reference

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。
