JavaScript Access Local Variable with Same Name in Inner and Outer Scope

Question

Given the following JavaScript:

var someFunction = function(id) {
  //do some stuff
  var modifyId = function(id) {
     //do some stuff
     outer.id = id;          


        

Answer 1

Unfortunately you can't. By naming the parameter in the nested function id, you've shadowed the parameter in the outer function. Javascript contains no facility for accessing the shadowed name. The only option is to choose a different name for one of the variables.
