Javascript Higher Order Functions Example

We provide you a clear explanation and examples about higher-order functions in Javascript 

Higher-Order function 

A higher-order function has a lot of functions to returns a value in javascript. In functional programming, the higher-order function plays a big role. Higher-order function, it's a powerful way. We probably used the higher-order function at any time. It has three higher-order functions, they are map, filter, and reduce.
Map-array of the list.
In a simple term of higher-order function is taking a function as arguments in javascript
Filter-predicate the list of elements.
Reduce-function to be initial value and array. Runs the function also.
A higher-order function takes the parameters for other functions. It's also a first-class value. Breaking the invariants in the higher-order function becomes a violation of encapsulation. The higher-order function used to reduce the redundant code. It also supports the programming language like JavaScript, Go, python, c++, c#. It also has the parameter function or return function. Higher-order function has two types of function(i.e) binary function and unary function. Haskell is a unary function because it takes one input for every function.

what is the concept of higher functions?

A higher-order function is a function that can take an alternative function as an argument and it will return a function as a response.

Advantage:
Higher-order functions solve a lot of problems in programming. They are three ways in the higher-order function to write a new function.
Function declaration
Function expression
Array function.

Javascript Higher-Order Functions

javascript higher-order function, it's well adapted for functional programming. It's single-threaded. JavaScript higher order also used in web programming. Node. js is more efficient for resources. The higher-order function also based on the first-class function concept. In higher-order function, some languages to implement the function. They are JavaScript, Haskell, claque, Scala, and Erlang.
Call back function is a concept in javascript that uses a lot and callback function is called by higher-order functions.
The Best Example for a higher-order function is the map functions because it takes a function as an argument.
Higher-order functions provide you to code simpler and more stylish code.

Example of  Higher-Order Functions

Javascript higher-order functions

These are the best example of Javascript Higher-Order Functions,
1. Sort 
2.Reduce
3.for loop
4.Filter 
5. Find
6.Map

Most of the developers are using the concept of closures in programming but never heard or use of higher-order functions in their code. Every developer is must know what is higher-order functions and why are higher-order functions in javascript.

javascript higher-order functions are easy and simple to understand to every common developer
