javascript - Looping through all of the items in the window object -
last night, got bored , thought of little idea little script. thinking how many built-in functions php has compared javascript , realized don't know how many functions javascript has. thought of writing script through window object including every object inside object , forth. wrote script , worked (tried on smaller object).
however, problem javascript wont let me loop though whole windows object.
i have tried:
for (var key in window) { console.log(key); } i tried:
var = object.create(window); (var key in a) { console.log(key); } both snippets of code give me:

in modern browsers object.getownpropertynames() , object.getprototypeof() properties of objects in prototype chain.
var obj = window; object.getownpropertynames(obj).foreach(function(name) { console.log(name); }); while(obj = object.getprototypeof(obj)); if want see separation of prototype objects, add line provides divider.
var obj = window; { object.getownpropertynames(obj).foreach(function(name) { console.log(name); }); console.log("============================="); } while(obj = object.getprototypeof(obj)); i think recall in firefox, globals don't appear until access them. may need little experimenting if find case.
