javascript - How to manipulate arrays with a custom function -

so have array each cell of array containing specific function.

var randomly = [   function(a) { return * - a; },   function(a) { return (a - 2) * (a - 1) * (a - 1); },   function(a) { return * + a; },   function(a) { return % 3; } ]; 

i'm creating function that takes input value (a) entire array , goes through each array cell individually, solves function. however, result of function becomes next function's input value. initial input value first function, , next function's input falue previous function's result.

to this, created loop...

var thefunction = function (input, queue){    (var = 0; < queue.length; i++){     queue[i](input);     } 

so, here i'm stuck...

how can call specific array along input value? used queue[i](input); not sure if that's valid. on appreciated.

you're close, "chain" functions, you'll need store return values, can re-use them:

var thefunction = function (input, queue) {   var result = input;    (var = 0; < queue.length; i++)     result = queue[i](result);    return result; } 

var randomly = [    function(a) { return * - a; },    function(a) { return (a - 2) * (a - 1) * (a - 1); },    function(a) { return * + a; },    function(a) { return % 3; }  ];    var thefunction = function (input, queue) {    var result = input;      (var = 0; < queue.length; i++)      result = queue[i](result);      return result;  }          console.log(thefunction(4, randomly));
