[JS Practice] execute multiple functions successively on a value

Title :

Execute multiple functions successively on a value


Write a generic function chainer that takes a starting value, and an array of functions to execute on it. Return the final value after execution is complete.


function add(num) { 
   return num + 1 

function mult(num) { 
   return num * 30 

chain(2, [add, mult]); // returns 90;

My solution :

function chain(input, fs) {
 var ret = input;
 for(var i=0; i<fs.length; i++) {
 ret = fs[i](ret);
 return ret;
