Learning JavaScript Data Structures and Algorithms

By: Loiane Groner, Aris Markogiannakis, Daniel Ostrovsky

Overview of this book

Data structures and algorithms are foundational topics for software developers. This easy-to-follow book from experienced developer and trainer Loiane Groner will help you to fill in the gaps in your knowledge – whether you’re a self-taught developer, you’re preparing for technical interviews, or you just want to write better code and improve your problem-solving skills. This fourth edition covers essential data structures, algorithms, and their usage in the context of JavaScript. You’ll follow examples in both JavaScript and TypeScript, in line with the latest standards and best practices, learning how to do complexity analysis along the way. New to this edition are LeetCode and HackerRank exercises at the end of each chapter, which you'll be guided through solving. You’ll also find brand-new chapters on the tries data structure, and string and math algorithms. By the end of the book, you will know how to develop programs using the best data structures and algorithms for the job.

Learning JavaScript Data Structures and Algorithms, Fourth Edition: Enhance your problem-solving skills in JavaScript and TypeScript

TypeScript fundamentals

TypeScript is an open source gradually typed superset of JavaScript created and maintained by Microsoft. Gradual typing is a type system that combines elements of both static typing and dynamic typing within the same programming language.

TypeScript allows us to add types to our JavaScript code, improving code readability, improving early error detection as we can catch type-related errors during development and enhanced tooling as code editors and IDEs offer better code autocompletion and navigation.

Regarding the scope of this book, with TypeScript we can use some Object-Oriented concepts that are not available in JavaScript such as interfaces - this can be useful when working with data structures and sorting algorithms. And of course, we can also leverage the typing functionality, which is especially important for some data structures. In algorithms that modify data structures, like searching or sorting, ensuring consistent data types within the collection is...
