Defining an array in javascript and storing the array name as a name

Question

By executing the below code in javascript:

var name=["Pankaj","Kumar"] ; for( var i=0;i<name.length;i++) { console.log("Hello "+name[i]); } 

For me, it should output:

 Hello Pankaj Hello Kumar 

But javascript outputs:

 Hello P Hello a Hello n Hello k Hello a Hello j Hello , Hello K Hello u Hello m Hello a Hello r 

If we change the name of the array as names , then it will exit as expected:

 Hello Pankaj Hello Kumar 

the name is not a javascript reserved keyword.

Could you tell me the reason for this behavior.

This question has it all

The name is already attached to the window where you are located as window.name , so do not use it or use IIFE as shown below to avoid pollution of the global namespace

 (function(){ var name=["Pankaj","Kumar"] ; for( var i=0;i<name.length;i++) { console.log("Hello "+name[i]); } })();
