JavaScript Data Structures and Algorithms: An Introduction to Understanding and Implementing Core Data Structure and Algorithm F

為了解決URL shortener的問題，作者Bae, Sammie 這樣論述：

Explore data structures and algorithm concepts and their relation to everyday JavaScript development. A basic understanding of these ideas is essential to any JavaScript developer wishing to analyze and build great software solutions. You'll discover how to implement data structures such as hash tab

les, linked lists, stacks, queues, trees, and graphs. You'll also learn how a URL shortener, such as bit.ly, is developed and what is happening to the data as a PDF is uploaded to a webpage. This book covers the practical applications of data structures and algorithms to encryption, searching, sorti

ng, and pattern matching. It is crucial for JavaScript developers to understand how data structures work and how to design algorithms. This book and the accompanying code provide that essential foundation for doing so. With JavaScript Data Structures and Algorithms you canstart developing your knowl

edge and applying it to your JavaScript projects today. What You'll LearnReview core data structure fundamentals: arrays, linked-lists, trees, heaps, graphs, and hash-tableReview core algorithm fundamentals: search, sort, recursion, breadth/depth first search, dynamic programming, bitwise operatorsE

xamine how the core data structure and algorithms knowledge fits into context of JavaScript explained using prototypical inheritance and native JavaScript objects/data typesTake a high-level look at commonly used design patterns in JavaScriptWho This Book Is For Existing web developers and software

engineers seeking to develop or revisit their fundamental data structures knowledge; beginners and students studying JavaScript independently or via a course or coding bootcamp. Sammie Bae is a data engineer at Yelp and has worked for the data platform engineering team at NVIDIA. He developed a de

ep interest in JavaScript during an internship at SMART Technologies (acquired by Foxconn), where he developed Node.js-based JavaScript APIs for serial port communication between electronic board drivers and a web application. Despite how relevant JavaScript is to the modern software engineering ind

ustry, there were no books that taught algorithms and data structures using JavaScript. Sammie understands how difficult these computer science concepts are and aims to make clear and concise explanations.

一個跨境電商詐騙網站協助偵測機制

為了解決URL shortener的問題，作者劉晏任 這樣論述：

隨著網際網路蓬勃發展，大多數人都曾有上網購物的經驗，增加方便性的同時卻也衍生出許多詐騙案例，而詐騙手法日新月異，過去常見的一頁式詐騙網站隨著時間逐漸演化為電商形式，相較於過去一頁式網頁粗糙的內容，電商形式的通常會有較精美的圖片及完整的框架，使消費者難就網頁內容判斷是否為詐騙網站。而市面上現存的產品，僅以安全或不安全作為回報，消費者無法得知更多的資訊，可能會因此被誤導。在本研究中，我們提出了一個框架，除了風險燈號提醒外，整合欲查詢網站的各項資料供消費者參考，並特別針對是否能與台灣有所連結進而提供相關的警告，讓消費者能在購物前有更充分的了解並評估自己使否處於風險之中。我們首先分析了台灣網路資訊中

心的詐騙網站資料集，透過將資料集進行分群，我們能初步了解目前的詐騙框架，進而可以識別未知網站是否與已知的詐騙群集有關，並利用此資料集來獲得詐騙網站的一些相關資訊占比，像是憑證頒發機構、網域存活時間或是註冊國家等等以利我們提出框架所列出的警告有所依據及參考。在實驗部分，本研究透過對比現存偵測詐騙網站工具的辨識結果以及使用者問卷調查，來驗證框架的有效性。實驗結果顯示，現存偵測詐騙網站工具 Scamadviser 成功辨識出的詐騙網站僅有54%，防詐達人為 79%，而本研究所提出的框架則在不考慮分群的前提下，可以判斷出87% 可能隱藏風險的詐騙網站；而在考慮分群結果後，在 Accuracy、Prec

ision、Recall及 F1­score 等各項指標均高於其他工具。使用者問卷調查方面，在僅提供網站頁面的階段，判斷詐騙網站與否的正確率僅有 51%，而電商型式的詐騙網站甚至僅有 37%，而在提供了一系列的資訊及警告後，正確率來到了 75%，再加上附加的商工登記公示資料查詢以及提供國內相關法律及自救程序，最終有 91% 的使用者認為此框架對於判斷詐騙網站是有效的。
