Refactoring is about improving the design of existing code. It is the process of changing a software system in such a way that it does not alter the external behavior of the code, yet improves its internal structure. With refactoring you can even take a bad design and rework it into a good one. This book offers a thorough discussion of the principles of refactoring, including where to spot opportunities for refactoring, and how to set up the required tests. There is also a catalog of more than 40 proven refactorings with details as to when and why to use the refactoring, step by step instructions for implementing it, and an example illustrating how it works The book is written using Java as its principle language, but the ideas are applicable to any OO language.
Features
The first update to a classic that is the standard reference for refactoring in over 15 years
Enhanced, web-based features including interactive examples, video snippets, code highlighting
Extensive use of JavaScript examples
New to This Edition
Martin Fowler is retaining everything that made Refactoring one of the world’s most popular and influential computer books, while updating with JavaScript examples throughout (to address many programmers’ current preferences) and reflecting today’s programming paradigms. The book’s catalog of individual refactorings has been updated, revised, and expanded.
Martin Fowler is Chief Scientist at ThoughtWorks. He describes himself as “an author, speaker, consultant and general loud-mouth on software development.” Fowler concentrates on designing enterprise software: exploring what makes a good design and what practices are needed to create one.
《重构》第二版来了! 很高兴有机会能够提前阅读这本神奇的书籍!很多年前就已经阅读过第一版《重构》!那时候就给我很大的冲击!说实话,开始并没有对这一版抱有太大的希望!但是当翻开书卷的那一刻,我还是很庆幸没有因为自己的执念而放弃掉这样一本真心重构了的好书! 可以...
评分纵览武侠江湖,制胜法门不外两项,内功和外功。二者得一可天下去得,但最终皆入内外兼修之境 倚天是自内而外,先修内功九阳真经,然后以此为基础,加上太极拳和太极剑,最终成就天下第一高手 笑傲是自外而内,先学独孤九剑,后学吸星大法,最后学易筋经。 神雕也不外如是,玉女...
评分《重构》给我最大的收获,其实是想法而非技巧。 开发人员的完美主义倾向,容易变成他们做Big Design Up Front的驱动力。而在现实的环境中,时间、资源等约束条件,通常不会允许我们进行过于详细的设计。 我认为最好的做法是,轻量级的设计 + 适当的重构,迭代地开发出满足各...
评分无论你是初出江湖的编码小农,还是深耕多年的程序大牛,这本书都值得你深度品读。 常常我们说的代码简洁性、易读性、健壮性,都并非一日之功,需要在日常的迭代中不断持续的进行重构,重构的事情我们常常挂在嘴边,却往往无从下手,本书以作者丰富的编程经验和思想,总结了一套...
评分适合写过两年代码的开发人员的一本书。 示范代码难度不是很高,主要就是理解里面的一种精神了。 我才看了一章,希望能坚持看完。
虽然例子是用JS写的,思想都是通的。前几章看完帮助非常大,很多平时写代码时候会纠结的地方从这里可以找到答案。讲的原则可操作性非常强,很多思想可以直接影响现在的工作方式。具体每个重构技巧比较繁杂,没仔细看完,可以有需要再拿出来翻。印象深刻的几个点:“不要专门和老板说我要重构,而是作为功能的一部分”,“保持修改后的代码比现在的代码好”,“大部分情况:可读性>性能”,“profiling找性能瓶颈,直觉大部分情况是错的”解决。
评分比之第一版,更注重细节功夫,重构过程更完备更流程,更注重行为保持,大规模的重构全部删去。可以体现作者的理念:于细节处见成败。
评分第二版有了不少改进,比如代码换成了js(用的是最新的ES语法),重构都配了示意图。收获非常大。
评分比之第一版,更注重细节功夫,重构过程更完备更流程,更注重行为保持,大规模的重构全部删去。可以体现作者的理念:于细节处见成败。
