Javascript declaring a function in an Object

Question

I am looking at some old code and some of the functions are defined as option 1 and others as option 2.

Is there a difference between these function declarations:

Option 1

obj.util.test = function util$test(x){  
... 
}

Option 2

obj.util.test = function (x){
...
}

Answer 1

In this case they are both identical.

• In Options 1 property test is created using a named function.

• In Options 2 property test is created using a anonymous function.

Named functions are useful because can be seen in stack traces and call stacks.
