Is redeclaring variables redundant?

Hey guys an example.

 

var obj = {
  string:'aa',
  func:function(){
      var st = this.string
      //do stuff with st
  } 
}

well it depends... if you just use string then it is accessible to other methods within your object.  What you are doing there is creating a copy that is local and accessible only to that specific function.  IOW it is a question/matter of variable scope requirements.

kk thanks for the heads up.
