What are the differences between higher-order functions and regular functions?

What are the differences between higher-order functions and regular functions?

Higher-order functions are functions that can take other functions as arguments or return them as results, while regular functions do not have this capability.

Can you give me an example of a higher-order function?

Sure! A common example is the map function, which takes a function and applies it to each element in an array.

How do higher-order functions improve code readability?

They allow for more abstract and concise code, making it easier to understand the intent behind operations on data.

Are there any performance drawbacks to using higher-order functions?

In some cases, higher-order functions can introduce overhead due to additional function calls, but the trade-off is often worth it for improved readability.

When should I use higher-order functions?

Use them when you need to manipulate or transform data in a flexible way, especially in functional programming paradigms.
