Algorithms and data structures are much more than abstract concepts. Mastering them enables you to write code that runs faster and more efficiently, which is particularly important for today's web and mobile apps. Take a practical approach to data structures and algorithms, with techniques and real-world scenarios that you can use in your daily production code, with examples in JavaScript, Python, and Ruby. This new and revised second edition features new chapters on recursion, dynamic programming, and using Big O in your daily work.

算法和数据结构不仅仅是抽象概念。掌握它们使您能够编写运行更快、更高效的代码，这对于当今的web和移动应用程序尤为重要。对数据结构和算法采取实际的方法，使用可以在日常生产代码中使用的技术和真实场景，并以JavaScript、Python和Ruby为例。这个新的和修订的第二版的特点是关于递归、动态编程和在日常工作中使用大O的新章节。
