Pattern of the Day

Simple explanation

You want to travel to work. You can take a car, bus, or bike. The destination stays the same, but the way you get there changes. Each transportation method is a different strategy. You pick the best one depending on the weather and how much time you have.

Payment Methods

"A store accepts multiple payment methods: credit card, debit card, or PayPal. The checkout process is the same, but the actual payment algorithm differs. The store doesn't care how you pay—it just needs a payment strategy that works."

Use it when

• ✓You have multiple ways to solve a problem and need to select at runtime
• ✓You want to avoid conditional statements (if/else or switch) scattered throughout code
