Here's an example of how we might document it: /* * Make a TCP connection to the given IPv4 address. On the other hand, errors are something you may not see it coming like stack over flow or not enough memory. Patterns for writing functions We've talked about how to handle errors, but when you're writing a new function, how do you deliver errors to the code that called your function? That is bad.
This works very well, and is widely used. Errors are inevitable, it’s what you do about them that counts. I speak only for myself, not for them. Well I'll accept later and that will give more people a chance to weigh in. –Josh Apr 7 '10 at 0:38 add a comment| up vote 4 down vote The ECMAScript

Coffeescript Try Catch Is there any reasoning behind disregarding what someone has to say because of their choice of desktop OS? You should run your programs using a restarter that will automatically restart the program in the event of a crash. This is strongly recommended.
For example, if the user gave you invalid JSON, it's not going to help to try parsing it again. programmer errors: introduction to two fundamentally different kinds of errors Patterns for writing functions: general principles for writing functions that produce useful errors Specific recommendations for writing new functions: a checklist If you believe Murphyʼs law, anything that can go wrong, will go wrong! What I like is now errors will unwind the stack which is super helpful in debugging.
Actually the ECMAScript spec calls the "Error Exceptions"! –Josh Apr 6 '10 at 18:42 2 Yep, all the standard exception constructors use Error rather than Exception... SyntaxError Creates an instance representing a syntax error that occurs while parsing code in eval(). You may remember the stack of function calls that was mentioned in chapter 3. The unit tests show how it is used.
