javascript - Use a method in a callback -

question being edited. sorry changes. please don't provide answers @ moment :)

if declare object in javascript:

var myobject = {  function myfunction() {     console.log('hi!');   } }  

why errors?

wouldn't rather be:

var myobject = {     myfunction : function(){         console.log('hi!');     } } 

how call method:

myobject.myfunction()
