Question

On the front page for MooTools, it says:

MooTools code respects strict standards and doesn’t throw any warnings.

I like MooTools, but having recently read The art of throwing JavaScript errors, I’m a bit confused as to why ‘not throwing any warnings’ is a feature. If a library doesn’t tell you when there’s an error (which may be caused because you are using it incorrectly), how are you going to fix the problem?

Why wouldn’t you want a library to throw errors?

Thanks,

Steve

Answer 1

Some javascript frameworks throw warnings due to rules being bent to achieve cross-browser support. I believe that MooTools’ claim is that they don’t throw any warnings to the browser in that sense, as opposed to the you doing something wrong with it sense.
