海外TECH	DEV Community	Higher-Order Functions — JavaScript	https://dev.to/fantom/higher-order-functions-javascript-5919	Higher Order Functions ー JavaScriptHigher order functions are an important and powerful concept in programming which allows you to write more flexible and modular code In JavaScript they are functions which uses other callback functions either by taking them as arguments or by returning them as output In JavaScript we have a few higher order array functions they include The Map function this is an higher order function which takes an array and a function as arguments and returns a new modified array which is the result of applying the function to each element of the previous array let array create functionfunction multiply p return p pass function as an argumentconst map array map multiply console log map expected output Array The Filter function this is an higher order function which takes an array and a function as arguments but in this case only returns a new array of elements which pass a given condition in the function let array filters out only numbers greater than const result array filter x gt x gt console log result expected output Array The Reduce function this is an higher order function that takes an array and a function as arguments but it returns only a single value that is the result of applying the function to each element of the array in a specific order This could be confusing so let s use a common and easy example straight from MDN MDN Web Docs The MDN Web Docs site provides information about Open Web technologies including HTML CSS and APIs for both Web sites and progressive web apps developer mozilla org to explainconst array const initialValue const sumWithInitial array reduce accumulator currentValue gt accumulator currentValue initialValue console log sumWithInitial Expected output The reducer walks through the array element by element at each step adding the current array value to the result from the previous step this result is the running sum of all the previous steps ーuntil there are no more elements to add Read more here The Sort function this is a higher order function that takes an array and a function as arguments and returns the reference to the same array now sorted according to the results of applying the function to each element This could however be used by default where it considers all elements as strings and sorts them in ascending order without a function argument for example const names Michael Amy John Faith Dan the sort function in defaultnames sort console log names expected output Array Amy Dan Faith John Michael However when we need to sort out other things apart from strings like numbers for instance then we will need to add a function to handle that Here s an example for sorting numbersconst array function that sorts by going through and return the lowest of two numbersfunction numSort a b return a b calling the sort function with the numSort callback functionarray sort numSort console log array Expected result The For Each function this is a higher order function that takes an array and a function as arguments and applies the function to each element of the array It does not return a new array but just performs an action on each element of the same array const foods pizza spaghetti food from Chowopa com burgers applies this function on each element in the foods arrayfoods forEach food gt let statement I am hungry maybe I ll get food console log statement Higher order functions provides an easier way for you to write more concise and expressive code and could also get rid of the need to write complex loops or conditional statements I hope you found this useful Ciao	2023-01-02 01:22:12
