If you've ever felt the exhilaration of cracking a thorny problem or the joy of witnessing elegant code that challenges your mind, then this book is tailor-made for you. Prepare yourself to dive into a diverse array of mind-bending JavaScript brain teasers. Each puzzle is more than just a code exercise; it's a gateway to unlocking new insights and honing your abilities. As you work through the challenges, you'll learn to think pragmatically, optimize your code for efficiency, and avoid hidden pitfalls that can catch you off guard. What's more - the puzzle format will help you remember what you've learned!
Over the years, JavaScript has gained a bit of a reputation for its quirky and unique characteristics. It's important for developers to be aware of these quirks to write more robust and predictable JavaScript code. In this book, we invite you on a journey designed to unveil the intricate nuances and peculiarities that define the language's essence.
Learn how to simulate function overloading, embed hidden information within objects, develop self-contained functions capable of maintaining their own local state, generate number sequences using functional programming, handle exotic forms of IIFEs, and prevent loss of precision when dealing with large numbers. Grasp concepts like closures, hoisting, symbols, execution context, event queue, text normalization, and more, one puzzle at a time.
Discover how to create your own custom objects that function as shortcuts, accurately calculate the length of emojis and Unicode characters, master the usage of the "this" keyword, leverage bitwise operators, and convert color names to hex notation for universal use across various platforms. Plus, steer clear of those usual traps and blunders that trip up JavaScript developers.
Forget passive learning. With JavaScript Brain Teasers, you'll actively engage with code puzzles that require creative thinking and problem-solving, which help you memorize difficult concepts.
What You Need:
Certain code examples take advantage of recently introduced JavaScript features. Therefore, it's important to use a JavaScript environment that supports ECMAScript 2020 or a newer version. The simplest way to experiment with the examples is use your browser's console. Just make sure your browser is up-to-date.

如果你曾經感受過解決棘手問題的興奮,或者見證了挑戰你思維的優雅代碼所帶來的喜悅,那麼這本書就是為你量身打造的。準備好深入探索各種令人腦洞大開的JavaScript謎題吧。每個謎題不僅僅是一個代碼練習,更是通往新見解和技能提升的門戶。通過解決這些挑戰,你將學會實用思維,優化代碼效率,避免意想不到的隱藏陷阱。更重要的是,謎題的形式將幫助你記住所學內容!
多年來,JavaScript因其古怪而獨特的特性而聞名。開發人員需要了解這些特點,以編寫更健壯和可預測的JavaScript代碼。在這本書中,我們邀請你踏上一段旨在揭示定義語言本質的微妙細節和特殊性的旅程。
學習如何模擬函數重載,嵌入對象中的隱藏信息,開發能夠維護自己本地狀態的自包含函數,使用函數式編程生成數字序列,處理奇特形式的立即執行函數表達式,以及在處理大數字時防止精度損失。一次解決一個謎題,掌握閉包、提升、符號、執行上下文、事件隊列、文本正規化等概念。
發現如何創建自己的自定義對象作為快捷方式,準確計算表情符號和Unicode字符的長度,掌握'this'關鍵字的使用,利用位運算符,並將顏色名稱轉換為通用的十六進制表示法,以在各種平台上使用。此外,避免那些常見的陷阱和錯誤,讓JavaScript開發人員不再絆倒。
忘掉被動學習吧。通過《JavaScript腦筋急轉彎》,你將積極參與需要創造性思維和解決問題的代碼謎題,這有助於你記憶困難的概念。
你需要什麼:
某些代碼示例利用了最近引入的JavaScript功能。因此,使用支持ECMAScript 2020或更新版本的JavaScript環境非常重要。實驗這些示例的最簡單方法是使用瀏覽器的控制台。只需確保你的瀏覽器是最新版本即可。
