How can I debug higher-order functions in JavaScript?
Debugging higher-order functions can be tricky. You can start by using console.log to trace the values being passed.
What if the function is returning undefined?
Check if the inner function is being called correctly. Ensure that you're returning the expected value from it.
Are there any tools that can help with this?
Yes, tools like Chrome DevTools allow you to set breakpoints and inspect the call stack, which can be very helpful.
Can you give me an example of a higher-order function?
Sure! A common example is the map function, which takes a function as an argument and applies it to each element in an array.
