What are some practical use cases for function factories in programming?

Function factories are useful for creating functions dynamically. They can be used for creating event handlers, customizing behavior, or generating functions with specific configurations.

Can you give me an example of a function factory?

Sure! A simple example is a factory that creates multiplier functions. You can create a function that multiplies by a specific number like this: function createMultiplier(multiplier) { return function(x) { return x * multiplier; }; }.

How do function factories improve code reusability?

Function factories enhance code reusability by allowing you to create multiple functions with similar behavior but different parameters, reducing redundancy.

Are there any performance considerations when using function factories?

Yes, while function factories can improve code organization, they may introduce overhead due to the creation of multiple closures. It's important to balance flexibility with performance.
