Reduce Higher Order Functions

*Reduce Higher Order Functions *

Learning with the help of exapmle :-

const arr =[2,3,4,5,6];

// c is a procedural language
// c++ and java is a object oriented language
// javascript is a functional programming language

//reduce returns only single time after executing the whole program

let addition =arr.reduce(function(sum,value){
let updatedsum =sum+value;
return updatedsum
},0)

console.log(addition);

// 👉ans ->20

let multiplication =arr.reduce(function(product,value){
let updatedproduct =product*value;
return updatedproduct
},1)

console.log(multiplication);

// 👉ans->720

//📌📌ReduceRight
// (It is same as reduce , only diffrence is that it runs from right)
let addition1=arr.reduceRight(function(sum,value){
let updatedsum1=sum+value;
return updatedsum1
},0)

console.log(addition1);

// ans->20
