What Are Higher-Order Functions?
Higher-order functions are functions that either accept other functions as arguments or return functions as output. They enable developers to reduce the complexity of their code and make it more efficient. Higher-order functions are important in functional programming, as they enable developers to write programs in a declarative style, which is more concise and easier to read.
Types of Higher-Order Functions
There are several types of higher-order functions including map, reduce, filter, and compose. Map is used to transform a list of values into a new list. Reduce is used to take a list of values and combine them into a single value. Filter is used to filter a list of values based on a given criteria. Finally, compose is used to combine multiple functions into a single function.
Benefits of Using Higher-Order Functions
The main benefit of using higher-order functions is that they enable developers to create more efficient and reusable code. By using higher-order functions, you can reduce the complexity of your code and make it easier to read and understand. Additionally, higher-order functions can help you create more modular code that can be reused in different contexts.
