These functions are a powerful feature of the language that allow you to write concise and expressive code. The best way to learn higher order functions (and likely the most “real-world”) is to look at “map()” and “filter()”. Both take functions as arguments where the function is applied to each element in an array. Map For example, consider the map function, which is used to apply a function to each element of an array and return a new array containing the results. The map function is a higher-order function because it takes a function as its argument, in this case the function to apply to each element of the array.
