JavaScript function declaration

Question

Are the JavaScript code snippets given below some sort of function declaration? If not can someone please give an overview of what they are?

some_func = function(value) {
    // some code here
}

and

show:function(value){
   // some code here
}

Answer 1

The first one is simply creating an anonymous function and assigning it to a variable some_func. So using some_func() will call the function.

The second one should be part of an object notation

var obj = {
  show:function(value){
    // some code here
  }
};

So, obj.show() will call the function

In both cases, you are creating an anonymous function. But in the first case, you are simply assigning it to a variable. Whereas in the second case you are assigning it as a member of an object (possibly among many others).
