# Strategy Pattern

Use the Strategy pattern when you have multiple algorithms for the same task and want to select one at runtime. Instead of complex if/else chains, define a common interface and implement it with different strategies. This enables adding new behaviors without modifying existing code. Common uses: payment processors, shipping calculators, validation rules.
