I have just begun to learn YUI, and have a question about the YUI.use() constructor.

I currently have 10 javascript files in my project and every file is coded like this:

file1.js:
YUI().use("a","b","c", function(Y) {
...
});

file2.js:
YUI().use("a","b","c", function(Y) {
...
});

file3.js:
YUI().use("a","b","c", function(Y) {
...
});

etc.

I have all 10 javascript files included in each html page, but I am wondering if the code has to be repetitive like this, to use the same modules over and over again?

I see what you're doing, but with your example, I still would have to repeat the same modules for each js file using the "requires" attribute, so why is YUI.add() preferred over YUI.use() when both approach work the same?

Relevant documentation on YUI().use() and YUI.add() is here:
