That one pipeline question

gistfile1.js

// Make a function called pipeline that accepts a value as a parameter, as well as any number of functions as additional parameters.
// The function will return the value that results from the first parameter being used as a parameter for the next function and so on.

var double = function(val) { return val * 2; }
var addOne = function(val) { return val + 1; }
var addThree = function(val) { return val + 3; }

/**
 * Given an initial value and any number of function arguments,
 * returns the value obtained by applying each function to the
 * result of the previous one.
 */
function pipeline() {
  // implementation
}

console.log(pipeline(5, double)) // should return 10
console.log(pipeline(5, double, addOne)) // should return 11
console.log(pipeline(3, addThree, double, addOne)) // should return 13
console.log(pipeline(0, addOne, addOne, addOne, addOne, addOne)) // 5
