What is the difference between function factories and regular functions?

Function factories are functions that return other functions, while regular functions simply perform tasks and return values.

Can you give me an example of a function factory?

Sure! A function factory could be a function that creates a multiplier function. For example, function makeMultiplier(factor) { return function(x) { return x * factor; }; }.

How do I use the multiplier function created by the factory?

You can use it like this: const double = makeMultiplier(2); console.log(double(5)); // Outputs 10.

Are there any advantages to using function factories?

Yes, they allow for more flexible and reusable code, enabling you to create customized functions on the fly.
