bro, you are the best teacher out there

[@user-qt1wn9l]

Sir, you are my last hope for any programming topic. Thank you for your very simple explanation

[@sailokeshchirumarri5727]

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);

[@aten488]

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

[@suvarnasuvi20]

I used all different values and got the exact same sum...crazy😅

[@bommasanivenkataramana656]

Thank you Man...

[@AtishDMello]

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?

[@amazingspiderman7897]

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
