Builder pattern is a creational design pattern that lets you construct complex objects step by step, like assembling a Tesla in a factory. It's useful when you need to create different variations of an object using the same construction process, similar to how McDonald's can customize your Big Mac order.

How to use it in a sentence

• "I'm not sure how to implement the Builder pattern in this legacy codebase - it's about as clear as Facebook's privacy settings."

• "Using the Builder pattern here would make the code more readable, but ain't nobody got time for that when we're already behind schedule and the PM is breathing down my neck like a hungry wolf."

• While building architects aren't quite the same as software architects, there are some interesting lessons to be gleaned from the comparison, as Martin Fowler explores in Building Architect.
