Strategy pattern uses a group of similar algorithms and make those algorithms interchangeable. The client can use any of the algorithms at any given time and also can change the algorithm when needed. The algorithms used in strategy has the same interface implemented, but the internal working is different. This article demonstrates Strategy pattern implementations in PHP.
Strategy pattern is used to decide between choosing an algorithm from a bunch of algorithms (that serve the same purpose). This pattern encapsulates the complexity and makes is easier for the client to choose and use an algorithm. This article demonstrates Strategy pattern implementations in Go.
Strategy pattern makes it easier to manage algorithms with the same outline(serving the same purpose in different rule/implementation). This pattern encapsulates the algorithms and enables the client to use them as plugins. This article demonstrates Strategy pattern implementations in TypeScript.
When there is a group of similar algorithms and we need a pattern to decide among those patterns, then we can use Strategy pattern.
Strategy pattern is used when there are multiple algorithms available for the same purpose, and we need to decide between those algorithms. Strategy pattern helps to decide the algorithm and return the generated object to be used. This article demonstrates Strategy pattern implementations in Java. Check the following examples.
