After I dug into it further, it wasn't surprising that while they are totally different it was very informative to understand how it can affect code architecture. This is the difference between a function declaration and an anonymous function expression.Īt first I remembered this concept and syntax back while in college but never have had chance to use it.
So when I was reviewing some code it was quite unusual for me to see the function definition as “ var = function()”.
