A completely stupid idea. It adds a thrown exception that functions solely as a goto.

At least with a GOTO you can get back to where you were - much more difficult with exceptions.

True, but then I'm a purist. I haven't used a goto statement in over 20 years. I will admit I use break and continue, but they are 'structured' to my way of thinking.

Did I miss something?
An exception is more than a goto, because it can jump outside of the current scope. This is very useful for aborting work that has run into a serious error, when it is appropriate to exit a chain of function calls and recover from a known point well down the stack. That's actually the only thing I use exceptions for. In most cases, such as a bad argument, the function should simply return a failure result instead.
EDIT: It looks like the code could well be overusing exceptions when returning a failure result would be more appropriate, so that's probably what I missed.

The 'guard' code from the article was this:
fun guard() {
if (!condition1) {
throw Exception1()
}
doThings1()
if (!condition2) {
throw Exception2()
}
doThings2()
if (!condition3) {
throw Exception3()
}
doThings3()
}This call needs to be surrounded by a try...catch in order to exactly reproduce the functionality of the original. I'm not sure which language is used for the original code; I think it may be Javascript, but the fun keyword is odd.
In any case, throwing an exception in lieu of nested conditionals or a goto is overly complicated and error-inducing. Imagine debugging this sort of nonsense when the catch misses one of the exceptions thrown.

It's so sad that other programmers that I may end up working with at some point read that drivel and adopt it.

Hi Marc, Perhaps my memory is flawed, but, I seem to recall eyeballing code of yours that used preventive filters in this way.
I'd appreciate your comments on my post below !

I believe in anticipating/handling errors in parameter data before you get to the juicy parts, and I think guard clauses are a good example of a strategy for that. I also think liberal use of Try/Catch for things like file-ops is a good thing.
Guard clauses' "virtual isolation" at the start of a method is, imho, "separation of concerns." You can easily comment them out, remove them, as conditions/state management require.
However, there are other strategies.
What I'd like to see is a radical extension of Attributes in C# that do AOP-like transformations, and, internally generate the equivalent of guard clauses: there's already an example of that in the semantics of the Nullable attributes: [^].

According to Daniel, while the practice of software development has changed in the past 20 years, SOLID principles are still the basis of good design. A lot of software architecture makes me want to hit the liquids

Has it ever been? 99% of the software I see is less architecture and more spontanoeus growth, like a shrubbery.

Large systems grow out of small ones, so the shrubbery aspect is almost a given. Trying to build a large system from scratch virtually guarantees failure, and a system that isn't growing usually doesn't have long to live. The problem is that a system's architecture often doesn't evolve with it, assuming that it had one in the first place.

Yep but it has to be a planned and structured growth, not cancer-like.
Ah yes, that escrescence there was made to support vendor XYZ, it's no longer necessary but it has been used as a base for that other escrescence for when we experimented with rubbing methylene on the code, now if we remove it it stops working.
