What's the best way to loop through a set of elements in JavaScript?

Question

In the past and with most my current projects I tend to use a for loop like this:

var elements = document.getElementsByTagName(\'div\');
for (var i=0; i

        

Answer 1

I like doing:

 
var menu = document.getElementsByTagName('div');
for (var i = 0; menu[i]; i++) {
     ...
}

There is no call to the length of the array on every iteration.
