using var keyword in nested functions [duplicate]

Question

I have found myself writing a lot of functions comprising of nested functions.

I like to use this pattern when doing so, as I find them easy to find again using the eclipse outline view

var outer_func = function(){

  var inner_func1 = function(){
  //code
  }
  var inner_func2 = function(){
  //code
  }

}

My question: Is there any scoping differences if I drop the var keyword from the nested/inner functions?

thanks for any advice.

Answer 1

If you leave off the inner var keyword, then you will be creating global functions named inner_func1 and inner_func2. Keep the var.
