First thing fresher do think about any programming language is where they use these programs. I think along with coding, their applications in different business processes could be of more use.

let arr = [1,2,3,4,5,6,7,8]; let result = arr.filter (n => n%2=== 0 ) .map ( n => n*2) .reduce ((x,y) => x+y ); /*arr.forEach(n =>{ console.log(n) }) */ console.log(result);

This was awesome.Thank you. My question is where did the a,b come from? or is it a default value to reduce?

what is the order that the methods are executed, For the first example nums.filter (n=>n%2==0).map(n=>n*2).forEach (n=> console.log(n)); Here is it filter then map then forEach For the second example let result = nums.filter (n=>n%2==0).map(n=>n*2).reduce((a,b)=>a+b); So for here it should be filter then map then reduce right?

Hi Atish, Always it is going to be executed from left to right. both filter and map methods are going to return an array, so we are chaining the resultant array to the next one by using dot (.) operator So yes, in first case it is filter -> map -> forEach and in second example filter -> map -> reduce
