Function definition patterns

/*** function statement vs variable ****/

function myFunc(){}
// vs
var myFunc = function(){};



/***** Argument signature *****/

// Standard
function standardFunction(arg1, arg2){
  
  // Argument type detection allows more flexible/optional arguments
  if (typeof arguments[0] == "string")
    // first arg is a string
    arguments[0];
}


// { name: value } pairs
function useObjectAsArguments(args){
  
  args.name;
  
  // this way, all arguments can be optional, passed in any order, and accessed by name
}
