It is a field guide for developers who learned by building, Googling, shipping, debugging, and figuring things out the hard way.\u003c\/p\u003e\n\n\u003cp\u003eInside, you’ll learn how to recognize the hidden patterns behind slow code:\u003c\/p\u003e\n\n\u003cp\u003eWhy some lookups stay fast no matter how much data you have\u003cbr\u003e\nWhy innocent-looking loops can quietly become expensive\u003cbr\u003e\nWhy arrays, maps, sets, stacks, and queues behave differently\u003cbr\u003e\nWhat O(1), O(log n), O(n), O(n²), and worse actually mean\u003cbr\u003e\nHow binary search, sorting, hashing, and memoization show up in real code\u003cbr\u003e\nHow to talk about performance clearly in code reviews and interviews Every concept is explained with a nickname, a real-world analogy, a short JavaScript example, and a “spot it in the wild” section so you can connect the idea to code you actually write.\u003c\/p\u003e\n\n\u003cp\u003eBig O is not about memorizing math. It is about knowing where the cliffs are before your app drives off one.\u003c\/p\u003e\n\n\u003cp\u003eIf you are self-taught, bootcamp-trained, AI-assisted, or simply tired of pretending that algorithm talk makes sense, this book will give you the mental model you should have had years ago.\u003c\/p\u003e","brand":"ANT","offers":[{"title":"Ebook","offer_id":67923989299445,"sku":"YSL50970","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/8774\/8597\/files\/71xFCxccAHL._SY1500.jpg?v=1793672359","url":"https:\/\/www.newbooks.store\/products\/b0h8st5gcy","provider":"NewBooks","version":"1.0","type":"link"}
