jambda.js

var first = function(){return 'first';},
  second = function(){return 'second';},
  func_one = function(someFunction, someValue){someFunction(someValue);},
  func_two = function(anotherFunction, anotherValue){anotherFunction(anotherValue);};

function say(word) {console.log(word);}
function speak(anotherWord) {console.log(anotherWord);}

/*
 * run the two functions above
     func_one(say, "hello -- function executing say");
     func_two(speak, "world -- function executing speak");
*/

function runFunctions(a,b) {
  console.log(a());
  console.log(b());
}

function runFunctionsTwo(a,b) {
  return a + b;
}

runFunctions(first, second);
runFunctionsTwo(func_one(say,'hello'),func_two(speak,'world'));
