程序员对代码所做的为了满足短期利益代码改动，或再没有完全清楚增个架构下的改动，都很容易是代码失去它的清晰结构，偏离需求或设计。而这些改动的积累很容易使代码偏离它原先设计的初衷而变得不可立即和无法维护。

Refactoring则帮助重新组织代码，重新清晰的体现结构和进一步改进设计。

-programmers to code done in order to meet short-term interest code changes or not entirely clear by a framework of the changes, it is easy to lose its code is a clear structure, depart from the demand or design. And the accumulation of these changes are easier to make code from its original intention of the original design has become an immediate and unable to preserve. Refactoring is helping to reorganize code, re - clearly reflected structure and further improve the design.
