About the Legacy Code course


In this course you will learn to work with legacy code. Understand which code should be modified, maintained, or rewritten. This is a course centered around legacy code, using PHP samples.

You’ll get to know: what’s legacy code, how we produce it (and which factors generate it). We’ll see lots of code, to train your instinct. We’ll see tools to deal with legacy code, understanding which one applies. Heuristics on saving, rewriting, throwing away components. All of this to make your software easy to work with again. After that, we’ll practice some TDD, to keep the software maintainable.

Certificate: After finishing the course, the student will receive a Completion Certificate.

Course Language: The course will be entirely in Spanish.
