NotesSubstitutability is a principle in object-oriented programming. It states that, in a computer program, if S is a subtype of T, then objects of type T may be replaced with objects of type S (i.e., objects of type S may be substituted for objects of type T) without altering any of the desirable properties of that program (correctness, task performed, etc.).FeedUnfurl
Notes"The Java ecosystem warps your brain into a mode of thinking where modularity patterns like DI and decoration are like ancient gods which can only be invoked with a great deal of pomp and ceremony. And I think that perspective tends to make it hard to see that other programmers use the same patterns, just with less fanfare. For an even better take on this topic than mine, read Jamis Buck’s classic account of writing and discarding two Ruby DI frameworks."Unfurl
