Hi All,
Thanks for the input...
As Andrew puts it, I'm not sold on this either.
However, when I see the plethora of ways we currently test to see if a
variable is undefined:
typeof example == 'undefined'
example === undefined
example == undefined (is that correct btw?)
I'm sure there's something we could do about this.
So there's another proposition I just though of, introducing the "is"
namespace:
var is = {
undefined: function(object) {
return object === undefined;
},
defined: function(object) {
return object !== undefined;
},
array: function(object) {
return typeof object == 'object' && object.constructor ==
Array;
},
element: function(object) {
return object.ownerDocument || object == window;
}
etc...
}
Which could be used like this:
if(is.array(example)) // do something
example = is.undefined(example) ? null : example;
example = is.defined(example) ? example : null;
Would this be a better idea?
Again, I'm just thinking out loud here, so any suggestions are
welcome.
Tobie
