JavaScript: var functionName = function() {} vs function functionName() {}
What’s the difference in those declarations (in JavaScript)?
Is there any differences between the following function declarations:
function wtf() {
}
lol = function() {
}
omg: function() {
}
?
Regards

1- Is a regular function declaration.
2- You declare an anonymous function and you store it in a variable.
3- The last one is part of an object notation :
var obj = {
omg:function(value){
// some code here
}
};

1st one :
creates a function at page level ( global level u can say )
2nd : Assings the function to variable 'lol'
3rd: Syntax error. :P
Exactly similar to: What's the difference in those declarations (in JavaScript)?

The first one isn't necessarily global, it depends which scope it's defined in. Actually, in the example given, the second one is global, assuming the variable isn't scoped before.

@deceze: If first 2 declared inside a function: are not they exact equivalent?

@raghavv this link explains it a bit more clearly.

@raghavv Nope, try it: jsfiddle.net/UtTGG

No, it’s the quite the same thing for each of them.
