Question

(function(){    
        pm.view.someFunction(arg) {
          arg is used here.
        }    

        pm.view.otherFun(){
          how can i pass the same arg here too
        }    
})();

how can i pass the same arg here in my other function. I heard that in closure we can access the variables which is above its context.

Answer 1

Closures mean that functions can use variables from their outer scope. Here’s an example:

function test(){
   var str = 'Hello',
   strFunc = function(){
     var s = str + ' world!';
     return s;
   };
   return strFunc;
}
var t = test();
console.log(t()); // Hello world!

The function returned by test (strFunc) is a closure. It “closes” around the local variable str. str is declared outside of strFunc, but since it’s in the same scope, it can access it.

In your example, you just have two functions (one of which accepts an arg parameter), that are in the same scope. arg is only in someFunction‘s scope, otherFun can’t access it unless it was passed as a parameter, or if arg was declared outside of the functions, like how str is declared before strFunc is.
