Is there an advantage to hosting the examples in an example folder versus the wiki in the repo?

I think that would be a great idea to add some example to help who is a noob or to help who have no experience with Javascript.

Hi Manoj,

We have to update functions_inside_conditional_blocks.md
New JS engines obaying conditional functional declarations.
Run the code of functions_inside_conditional_blocks.md in console:
output will be:

innerFunc: Inside if
innerFuncExpr: Inside if

Hi there!
Always good to see people wanting to help others! And it's a nice little collection :) .

However, there is a little misinterpretation concerning Functions inside methods and this variable and in this particular case, in a forEach function, there is no need to 'hard bind' any context.

The function in //1 is the callback of a forEach loop function.
A forEach function (Array.prototype.forEach) can take 2 arguments even if the second, the "this" argument, is somewhat less known. See Array.prototype.forEach

The snippet

...
this.myNickNames.forEach(
   function (nickName) {  // 1
    console.log(this.myName +' is also known as '+ nickName);  // 2
   }.bind(this)
);
...

could be replaced with

...
this.myNickNames.forEach(
   function (nickName) { console.log(this.myName +' is also known as '+ nickName); }, 
   this  // 2nd arg
);
...

How that's working? Let's try to build a minimal custom forEach function :

function forEach(array, callback, thisArg) {

  var length = array.length;
  var i = 0;

  for(i; i< length; i++){

    // Here, a forEach function applies the callback to thisArg
    callback.apply(thisArg, [array[i], i, array]);  
  }
}

So, I see a lot of people using var self = this statements when using foreach, map and others arrays manipulation functions, and that's not necessary.

And even better, we have now arrows functions with es2015.
Your snippet could be rewritten like this

...
this.myNickNames.forEach( 
   nickName =>  console.log(this.myName +' is also known as '+ nickName);  // Yeah!
);
...

That's all. Hope it can be useful!
And happy Js coding! ;)

Scope

let var const

function hi () { alert("hi") }

hi = function () { alert("hello") }

console.log(hi());  //"hello"

better

const hi = function () { alert("hi") }

hi = function () { alert("hello") }

console.log(hello);  // Uncaught TypeError: invalid assignment to const 'hi'

let obj = {};
obj = "string"; //"string"

better

const obj = {};
obj = "string";  // Uncaught TypeError: invalid assignment to const 'obj'
