Explain the concept of a higher-order function in Go.
- A function that returns an integer.
- A function that takes a function as an argument and/or returns a function as a result.
- A function that can be called only from within the same package.
- A function that cannot be tested.
In Go, a higher-order function is a function that takes one or more functions as arguments and/or returns a function as its result. This concept enables functional programming paradigms in Go, allowing you to write more flexible and reusable code. Higher-order functions are often used to implement functional constructs like map, reduce, and filter, which operate on collections of data. They promote code modularity and make it easier to reason about and test your code.
