Whoa! That is invalid ECMAScript that relies on browser-dependent syntax
extensions.
Why do that, when you can easily write the same code with valid syntax?
var slice = (function($slice){
try {
$slice.call(document.childNodes);
var slice = function(list){
return $slice.call(list);
};
} catch(e) {
slice = function(){
for(var r = [], i = 0, length = list.length; i < length; ++i)
r[i] = list[i]
;
return r;
};
};
return slice;
})(Array.prototype.slice);
Or:
var slice = (function($slice){
try {
$slice.call(document.childNodes);
return function(list){
return $slice.call(list);
};
} catch(e) {}
return function(){
for(var r = [], i = 0, length = list.length; i < length; ++i)
r[i] = list[i]
;
return r;
};
})(Array.prototype.slice);
