Suppose you want to use indexOf in a array.
http://www.cjboco.com/blog.cfm/post/indexof-problems-in-internet-explorer/
So, lets use the power of JS to fix JS, .... lets add indexOf to the prototype
http://stackoverflow.com/questions/948358/array-prototype-problem
Ooops, Array.prototype is global
var a = [1,2,3,4,5];
for (x in a){
// Now indexOf is a part of EVERY array and
// will show up here as a value of 'x'
}
So what you do? you use a library for that.
http://documentcloud.github.com/underscore/
http://api.jquery.com/jQuery.inArray/
$.each , _.each
$.inArray, _.include(
and a lot of other nice tools that make you happy.
People seems to think functional programming is not something to
avoid, but something that can be usefull.
