Using callbacks comes with many issues and indentation with curly braces jungle is but one of them. By passing a callback you are passing the control over to a potentially buggy code with undesired behaviour.
The callback problems are:
callback can be called once, twice, infinitely many times, or never, and you have no control over it
callback can be called in synchronous or asynchronous fashion
callbacks swallow exceptions and force developers to conventions
callbacks make writing the curlybraced and indented code easy
Yet the webpage only mentions the last one, from my point the least important one. Is it possible to at least mention that there are other, more serious problems, which actually turn this whole area into a real hell?
