[removed] enumerate global vars

Question

a = 123; // becomes global var

var b = 234; // local var

function f() {} // local func

g = function() {} // got a global func

now how to print

Answer 1

All global variables are stored on the window object in a browser. Alternatively, they are stored on the global or GLOBAL object in Node.js. You can enumerate that object's keys instead, but keep in mind that it will contain much, much more than user-defined globals.

Answer 2

Globals become attached to the global object, which in a browser is the window.

a = 123

is the same as

window.a = 123

Answer 3

How about:

var globals = window || global;
for (var key in globals){
  console.log(window[key]);
}
