Software Design/Always use the same way to do a thing

Checklist questions:

Examples

Collections.emptyList() vs. ImmutableList.of() in Java.

Why

• Consistency
• Easier to refactor
• Performance: less code is used => less code cache misses

Related

• Minimize the diff between implementations of a strategy
