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

var someFunction = function(id) {
  //do some stuff
  var oid = id;
  var modifyId = function(id) {
     //do some stuff
     // you can access the outer id via the oid variable
  }
}

But, yes, you should just rename one of the formal parameters.
