Conclusion:
Today, we addressed the fundamental concept of functional programming and functions as first-class citizens. In addition, we covered in detail how Higher-order functions can be employed in many contexts. Higher-order functions in JavaScript are an advantageous feature. They improve the functionality of standard functions and allow code to be communicated via actions, boosting its reusability and abstraction. Depending on the requirements, we could either use the built-in higher-order functions supplied by JavaScript libraries or construct our own to write composed and complicated functions.
