QUESTION
The strategy pattern is software a design pattern to select an algorithm at runtime. See this javascript implementation for reference.
See the linked page, how the example use different classes at runtime. But, what about if you just want to select one function? Is it worth encapsulate those functions in classes? Or just select the function to use, like in the next snipped:
...ANSWER
Answered 2018-Feb-05 at 14:32Just select the function directly.
Is it worth encapsulate those functions in classes?
No. It's hardly ever worth to encapsulate anything in a class
when you can do without - that many other languages cannot do without and require class
es for everything should not affect your choice in JavaScript.
Also don't forget that functions already are objects in JavaScript, they're instances of the Function
class. If you absolutely want to define an interface for them, just go for duck-typing their call
method.
