What are the best practices for using higher-order functions in JavaScript?

What are the best practices for using higher-order functions in JavaScript?

Higher-order functions are functions that take other functions as arguments or return them. Best practices include keeping them pure, using them for abstraction, and avoiding side effects.

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, returning a new array.

What should I avoid when using higher-order functions?

Avoid using higher-order functions for complex logic that can be hard to read. Also, be cautious of side effects that can lead to unpredictable behavior.

How do higher-order functions improve code readability?

They allow you to abstract away repetitive logic, making your code cleaner and easier to understand by focusing on what the code does rather than how it does it.
