Top 10 12 Reasons why Javascript is Better than PHP
- Functions that return objects can be treated like objects.
document.getElementsByTagName('ul')[0].innerHMTLworks the same asvar ul=document.getElementsByTagName('ul'); ul=ul[0]; ul.innerHTML;. But, for some silly reason,$xml->xpath('//ul')[0]->asXml()throws a bunch of errors. - Dots are prettier than arrows.
- It runs on someone else’s machine.
- It has a lisp. (All Hail the Mighty λ!)
- Only functions cause scope. (Oh, the hours tracking down an elusive bug that happened because the scope created by a
switchstatement in a php file caused one variable to be updated, but not another.) - You can do it in the browser.
- You can do it inline
- There aren’t a bajillion functions, and you can enumerate them easily.
- Firebug
- Prototype Chains
[EDIT]
Some more that I forgot about:
- Logical ANDs and ORs can be used for variable assignment.
function myFn(a) { a = a || 'default value'; }; - No dollar signs!! (unless you want them)

All hail firebug. That has been so instrumental in debugging AJAX stuff I’ve been working on. I used to hate javascript but have warmed up to it as it is so easy to manipulate the dom.
Good post.

PHP5 allows a function to return an object and have it accessed as well, e.g.:
function moo() {
return new Whatever;
}
echo moo()->someFunc();
The same cannot be done (to my knowledge) with accessing array elements right after calling the function, (moo()[0]…); however, the PHP5 SPL ArrayAccess class should be tested to see if it would in fact work. (where Whatever would implement ArrayAccess)
