I was reading that using anonymous functions in javascript is bad practice, because it can make debugging a pain, but I haven’t seen this for myself. Are anonymous functions in JavaScript really bad practice and, if so, why?
Nope, anonymous functions are used all over the place in JavaScript across the web. It may make debugging a little more difficult in spots, but not nearly enough to say that they shouldn’t be used.
For example, JQuery makes extensive use of them.
There are a lot of times when you want to use them over formally declared functions, such as when you want to limit their scope.
