JS console Lesson #1: declaring functions.

declaring.js

// 1. declare a "named" function
 function myNamedFunction(){ return true; }
 // assertions
 console.log(typeof window.myNamedFunction === "function"); // true
 console.log(myNamedFunction.name === "myNamedFunction"); // true
 
 // 2. declare anonymous function
 var myAnonymousFunction = function(){ return true; };
 //assertions 
 console.log(typeof window.myAnonymousFunction === "function"); // true
 console.log(myAnonymousFunction.name === ""); // true
 
 // 3. another way to declare
 window.anotherAnonFunc = function(){ return true; }
 console.log(typeof window.anotherAnonFunc === "function"); // true
 
 // 4. shows how to reference a func before it's declared 
 function outerFunc(){
  console.log(typeof innerFunc === "function"); // true (that's right)
  function innerFunc(){}
  console.log(window.innerFunc === undefined); // true : not a global function
 }
 outerFunc();
 
 // 5. shows difference between function "name" and variable name.
 var funcA = function funcB() { }
 console.log(funcA.name); // 'funcB' 
 

The idea for this course is that you can copy/paste this gist into your browser console and play around with the assertions. Which will hopefully help you better understand how javascript works.

Feedback greatly appreciated.
