Definition: A family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients that use it.

Simple Meaning: Strategy design pattern helps us avoid code duplication by providing us various algorithms/implementations to choose from for a particular abstract method/function or even overriding and all these algorithms are loosely coupled.
