Consider the following, we want to make a trivial "calculator" that takes two values and operates with them. It then displays that result in some way. what is an example diffusion And because JavaScript is so flexible it makes design patterns like the Strategy robust as we will see in this post. In this post, we will be going over the Strategy Design Pattern. This is a well known pattern that encapsulates one or more strategies (or algorithms) to do a task. These encapsulated strategies all have the same signature so the ...The strategy pattern (also known as the policy pattern) is a behavioral software design pattern that enables selecting an algorithm at runtime. Instead of implementing a single algorithm directly, code receives run-time instructions as to which in a family of algorithms to use. Wikipedia My problem1. "Each of these rest calls takes a different number of parameters but the response remains the same." doesn't sound like the case for a strategy pattern - typically different strategies still have the exact same interface. You can probably just pass all and let the strategy determine what it uses or not but it's a bit of a kludge. live music near me this sunday

Using the Strategy pattern, we define a set of related algorithm and encapsulate them in classes separated from the host class ( Encryptor ). Clients can choose the algorithm to use at run time. By doing so, we can easily add a new algorithm or remove an existing one without modifying the other existing algorithms or the host class.In the Strategy Design Pattern when there is a base ( Context) class and one Strategy it is like a function that calls the Strategy and returns the result (in other the words the same thing).
