Word of the Day: Daily updates on the latest technology terms

Word of the Day Daily updates on the latest technology terms | April 2, 2020 refactoring Refactoring 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," according to Martin Fowler, the "father" of refactoring. The concept of refactoring covers practically any revision or cleaning up of source code, but Fowler consolidated many best practices from across the software development industry into a specific list of "refactorings" and described methods to implement them in his book, Refactoring: Improving the Design of Existing Code. While refactoring can be applied to any programming language, the majority of refactoring tools were originally developed for the Java language. One approach to refactoring is to improve the structure of source code at one point and then extend the same changes systematically to all applicable references throughout the program. The result is to make the code more efficient, scalable, maintainable or reusable, without actually changing any functions of the program itself. Refactoring plays an important role in application modernization and moving legacy apps from a monolithic structure to microservices. Eric Raymond, a leading philosopher about program development, maintains that the concept of refactoring is consistent with the idea of get-something-working-now-and-perfect-it-later approach long familiar to Unix and open source programmers and hackers. The idea is also embodied in the approach known as extreme programming. Continue reading... Today's Takeaway "Refactoring is a vital part of software code maintenance. This restructuring process improves the code's readability and extensibility -- it might even address looming flaws before users experience their effects." - Stephen J.
