The Strategy Pattern: Kill Your If-Else Ladders

4 min read

The pattern behind every pluggable behavior: payment methods, spot assignment, ranking algorithms. Learn the shape, the code, and when NOT to use it.

Every LLD interview eventually reaches the same moment: a behavior that varies. Payment can be card, UPI, or wallet. Parking spots can be assigned nearest-first or cheapest-first. Feeds can be ranked by recency or relevance. Reach for if-else and you've told the interviewer everything they need to know. Reach for Strategy and the conversation changes.
